5 SCons - a software construction tool
15 - Replace print statements with calls to sys.stdout.write() so output
16 lines stay together when -j is used.
18 - Add portability fixes for a number of tests.
20 - Accomodate the fact that Cygwin's os.path.normcase() lies about
21 the underlying system being case-sensitive.
23 - Fix an incorrect _concat() call in the $RCINCFLAGS definition for
26 - Fix a problem with the msvc tool with Python versions prior to 2.3.
28 - Add support for a "toolpath" Tool() and Environment keyword that
29 allows Tool modules to be found in specified local directories.
31 - Work around Cygwin Python's silly fiction that it's using a
32 case-sensitive file system.
36 - Fix the ability to save/restore a PackageOption to a file.
40 - Make the Fortran scanner case-insensitive for the INCLUDE string.
44 - If no version of MSVC is detected but the tool is specified,
45 use the MSVC 6.0 paths by default.
47 - Ignore any "6.1" version of MSVC found in the registry; this is a
48 phony version number (created by later service packs?) and would
49 throw off the logic if the user had any non-default paths configure.
51 - Correctly detect if the user has independently configured the MSVC
52 "include," "lib" or "path" in the registry and use the appropriate
53 values. Previously, SCons would only use the values if all three
54 were set in the registry.
56 - Make sure side-effect nodes are prepare()d before building their
59 - Preserve the ability to call BuildDir() multiple times with the
60 same target and source directory arguments.
62 From Scott Lystig Fritchie:
64 - Fix the ability to use a custom _concat() function in the
65 construction environment when calling _stripixes().
67 - Make the message about ignoring a missing SConscript file into a
68 suppressable Warning, not a hard-coded sys.stderr.write().
70 - If a builder can be called multiple times for a target (because
71 the sources and overrides are identical, or it's a builder with the
72 "multi" flag set), allow the builder to be called through multiple
73 environments so long as the builders have the same signature for
74 the environments in questions (that is, they're the same action).
78 - Fix EnsureSConsVersion() so it checks against the SCons version,
79 not the Python version, on Pythons with sys.version_info.
81 - Don't swallow the AttributeError when someone uses an expansion like
82 $TARGET.bak, so we can supply a more informative error message.
84 - Fix an odd double-quote escape sequence in the man page.
86 - Fix looking up a naked drive letter as a directory (Dir('C:')).
88 - Support using File nodes in the LIBS construction variable.
90 - Allow the LIBS construction variable to be a single string or File
91 node, not a list, when only one library is needed.
93 - Fix typos in the man page: JAVACHDIR => JARCHDIR; add "for_signature"
94 to the __call__() example in the "Variable Substitution" section.
96 - Correct error message spellings of "non-existant" to "non-existent."
98 - When scanning for libraries to link with, don't append $LIBPREFIXES
99 or $LIBSUFFIXES values to the $LIBS values if they're already present.
101 - Add a ZIPCOMPRESSION construction variable to control whether the
102 internal Python action for the Zip Builder compresses the file or
103 not. The default value is zipfile.ZIP_DEFLATED, which generates
106 - Refactor construction variable expansion to support recursive
107 expansion of variables (e.g. CCFLAGS = "$CCFLAGS -g") without going
108 into an infinite loop.
110 - Fix calling Configure() from more than one subsidiary SConscript file.
114 - Add support for the bcc32, ilink32 and tlib Borland tools.
118 - Supply an error message if the user tries to configure a BuildDir
119 for a directory that already has one.
121 - Remove documentation of the still-unimplemented -e option.
123 - Add -H help text listing the legal --debug values.
125 - Don't choke if a construction variable is a non-string value.
129 RELEASE 0.94 - Fri, 07 Nov 2003 05:29:48 -0600
133 - Add several new types of canned functions to help create options:
134 BoolOption(), EnumOption(), ListOption(), PackageOption(),
139 - Fix use of CPPDEFINES with C++ source files.
141 - Fix env.Append() when the operand is an object with a __cmp__()
142 method (like a Scanner instance).
144 - Fix subclassing the Environment and Scanner classes.
146 - Add BUILD_TARGETS, COMMAND_LINE_TARGETS and DEFAULT_TARGETS variables.
150 - SGI fixes: Fix C++ compilation, add a separate Tool/sgic++.py module.
152 From Gary Oberbrunner:
154 - Fix how the man page un-indents after examples in some browsers.
158 - Fix the C and C++ tool specifications for AIX.
162 RELEASE 0.93 - Thu, 23 Oct 2003 07:26:55 -0500
166 - On POSIX, execute commands with the more modern os.spawnvpe()
167 function, if it's available.
169 - Scan .S, .spp and .SPP files for C preprocessor dependencies.
171 - Refactor the Job.Parallel() class to use a thread pool without a
172 condition variable. This improves parallel build performance and
173 handles keyboard interrupts properly when -j is used.
177 - Add support for a JARCHDIR variable to control changing to a
178 directory using the jar -C option.
180 - Add support for detecting Java manifest files when using jar,
181 and specifying them using the jar m flag.
183 - Fix some Python 2.2 specific things in various tool modules.
185 - Support directories as build sources, so that a rebuild of a target
186 can be triggered if anything underneath the directory changes.
188 - Have the scons.bat and scons.py files look for the SCons modules
189 in site-packages as well.
191 From Christian Engel:
193 - Support more flexible inclusion of separate C and C++ compilers.
195 - Use package management tools on AIX and Solaris to find where
196 the comilers are installed, and what version they are.
198 - Add support for CCVERSION and CXXVERSION variables for a number
199 of C and C++ compilers.
203 - Add test cases for the new capabilities to run bibtex and to rerun
206 From Ralf W. Grosse-Kunstleve:
208 - Accomodate anydbm modules that don't have a sync() method.
210 - Allow SConsignFile() to take an argument specifying the DBM
213 From Stephen Kennedy:
215 - Add support for a configurable global .sconsign.dbm file which
216 can be used to avoid cluttering each directory with an individual
221 - Fix (re-)scanning of dependencies in generated or installed
226 - The -Q option suppressed too many messages; fix it so that it only
227 suppresses the Reading/Building messages.
229 - Support #include when there's no space before the opening quote
232 - Accomodate alphanumeric version strings in EnsurePythonVersion().
234 - Support arbitrary expansion of construction variables within
235 file and directory arguments to Builder calls and Environment methods.
237 - Add Environment-method versions of the following global functions:
238 Action(), AddPostAction(), AddPreAction(), Alias(), Builder(),
239 BuildDir(), CacheDir(), Clean(), Configure(), Default(),
240 EnsurePythonVersion(), EnsureSConsVersion(), Environment(),
241 Exit(), Export(), FindFile(), GetBuildPath(), GetOption(), Help(),
242 Import(), Literal(), Local(), Platform(), Repository(), Scanner(),
243 SConscriptChdir(), SConsignFile(), SetOption(), SourceSignatures(),
244 Split(), TargetSignatures(), Tool(), Value().
246 - Add the following global functions that correspond to the same-named
247 Environment methods: AlwaysBuild(), Command(), Depends(), Ignore(),
248 Install(), InstallAs(), Precious(), SideEffect() and SourceCode().
250 - Add the following global functions that correspond to the default
251 Builder methods supported by SCons: CFile(), CXXFile(), DVI(), Jar(),
252 Java(), JavaH(), Library(), M4(), MSVSProject(), Object(), PCH(),
253 PDF(), PostScript(), Program(), RES(), RMIC(), SharedLibrary(),
254 SharedObject(), StaticLibrary(), StaticObject(), Tar(), TypeLibrary()
257 - Rearrange the man page to show construction environment methods and
258 global functions in the same list, and to explain the difference.
260 - Alphabetize the explanations of the builder methods in the man page.
262 - Rename the Environment.Environment class to Enviroment.Base.
263 Allow the wrapping interface to extend an Environment by using its own
264 subclass of Environment.Base and setting a new Environment.Environment
265 variable as the calling entry point.
267 - Deprecate the ParseConfig() global function in favor of a same-named
268 construction environment method.
270 - Allow the Environment.WhereIs() method to take explicit path and
271 pathext arguments (like the underlying SCons.Util.WhereIs() function).
273 - Remove the long-obsolete {Get,Set}CommandHandler() functions.
275 - Enhance env.Append() to suppress null values when appropriate.
277 - Fix ParseConfig() so it works regardless of initial construction
280 Extend CheckHeader(), CheckCHeader(), CheckCXXHeader() and
281 CheckLibWithHeader() to accept a list of header files that will be
282 #included in the test. The last one in the list is assumed to be
283 the one being checked for. (Prototype code contributed by Gerard
284 Patel and Niall Douglas).
286 - Supply a warning when -j is used and threading isn't built in to
287 the current version of Python.
289 - First release of the User's Guide (finally, and despite a lot
290 of things still missing from it...).
294 - Generalize the action for .tex files so that it will decide whether
295 a file is TeX or LaTeX, check the .aux output to decide if it should
296 run bibtex, and check the .log output to re-run LaTeX if needed.
300 - Split the non-SCons-specific functionality from SConf.py to a new,
301 re-usable Conftest.py module.
303 From Gary Oberbrunner:
305 - Allow a directory to be the target or source or dependency of a
306 Depends(), Ignore(), Precious() or SideEffect() call.
310 - Use the %{_mandir} macro when building our RPM package.
314 - Have the closing message say "...terminated because of errors" if
319 - On Win32 systems, only use "rm" to delete files if Cygwin is being
320 used. ("rm" doesn't understand Win32-format path names.)
322 From Christoph Wiedemann:
324 - Fix test/SWIG.py to find the Python include directory in all cases.
326 - Fix a bug in detection of Qt installed on the local system.
328 - Support returning Python 2.3 BooleanType values from Configure checks.
330 - Provide an error message if someone mistakenly tries to call a
331 Configure check from within a Builder function.
333 - Support calling a Builder when a Configure context is still open.
335 - Handle interrupts better by eliminating all try:-except: blocks
336 which caught any and all exceptions, including KeyboardInterrupt.
340 RELEASE 0.92 - Wed, 20 Aug 2003 03:45:28 -0500
342 From Charles Crain and Gary Oberbrunner:
344 - Fix Tool import problems with the Intel and PharLap linkers.
348 - Refactor the DictCmdGenerator class to be a Selector subclass.
350 - Allow the DefaultEnvironment() function to take arguments and pass
351 them to instantiation of the default construction environment.
353 - Update the Debian package so it uses Python 2.2 and more closely
354 resembles the currently official Debian packaging info.
358 - When the yacc -d flag is used, take the .h file base name from the
359 target .c file, not the source (matching what yacc does).
363 RELEASE 0.91 - Thu, 14 Aug 2003 13:00:44 -0500
367 - Support specifying a list of tools when calling Environment.Copy().
369 - Give a Value Nodes a timestamp of the system time when they're
370 created, so they'll work when using timestamp-based signatures.
372 - Add a DefaultEnvironment() function that only creates a default
373 environment on-demand (for fetching source files, e.g.).
375 - Portability fix for test/M4.py.
379 - Tighten up the scons -H help output.
381 - When the input yacc file ends in .yy and the -d flag is specified,
382 recognize that a .hpp file (not a .h file) will be created.
384 - Make builder prefixes work correctly when deducing a target
385 from a source file name in another directory.
387 - Documentation fixes: typo in the man page; explain up-front about
388 not propagating the external environment.
390 - Use "cvs co -d" instead of "cvs co -p >" when checking out something
391 from CVS with a specified module name. This avoids zero-length
392 files when there is a checkout error.
394 - Add an "sconsign" script to print the contents of .sconsign files.
396 - Speed up maintaining the various lists of Node children by using
397 dictionaries to avoid "x in list" searches.

400 so it's only calculated once.
402 - Fix use of the --cache-show option when building a Program()
403 (or using any other arbitrary action) by making sure all Action
404 instances have strfunction() methods.
406 - Allow the source of Command() to be a directory.
408 - Better error handling of things like raw TypeErrors in SConscripts.
410 - When installing using "setup.py install --prefix=", suppress the
411 distutils warning message about adding the (incorrect) library
412 directory to your search path.
414 - Correct the spelling of the "validater" option to "validator."
415 Add a DeprecatedWarning when the old spelling is used.
417 - Allow a Builder's emitter to be a dictionary that maps source file
418 suffixes to emitter functions, using the suffix of the first file
419 in the source list to pick the right one.
421 - Refactor the creation of the Program, *Object and *Library Builders
422 so that they're moved out of SCons.Defaults and created on demand.
424 - Don't split SConscript file names on white space.
426 - Document the SConscript function's "dirs" and "name" keywords.
428 - Remove the internal (and superfluous) SCons.Util.argmunge() function.
430 - Add /TP to the default CXXFLAGS for msvc, so it can compile all
431 of the suffixes we use as C++ files.
433 - Allow the "prefix" and "suffix" attributes of a Builder to be
434 callable objects that return generated strings, or dictionaries
435 that map a source file suffix to the right prefix/suffix.
437 - Support a MAXLINELINELENGTH construction variable on Win32 systems
438 to control when a temporary file is used for long command lines.
440 - Make how we build .rpm packages not depend on the installation
441 locations from the distutils being used.
443 - When deducing a target Node, create it directly from the first
444 source Node, not by trying to create the right string to pass to
447 - Add support for SWIG.
451 - Test portability fixes for FreeBSD.
453 From Gary Oberbrunner:
455 - Report the target being built in error messages when building
456 multiple sources from different extensions, or when the target file
457 extension can't be deduced, or when we don't have an action for a
460 - Provide helpful error messages when the arguments to env.Install()
463 - Fix the value returned by the Node.prevsiginfo() method to conform
464 to a previous change when checking whether a node is current.
466 - Supply a stack trace if the Taskmaster catches an exception.
468 - When using a temporary file for a long link line on Win32 systems,
469 (also) print the command line that is being executed through the
472 - Initialize the LIB environment variable when using the Intel
475 - Documentation fixes: better explain the AlwaysBuild() function.
479 - When the -debug=pdb option is specified, use pdb.Pdb().runcall() to
480 call pdb directly, don't call Python recursively.
484 - Add support for a platform-independent CPPDEFINES variable.
486 From Christoph Wiedemann:
488 - Have the g++ Tool actually use g++ in preference to c++.
490 - Have the gcc Tool actually use gcc in preference to cc.
492 - Add a gnutools.py test of the GNU tool chain.
494 - Be smarter about linking: use $CC by default and $CXX only if we're
495 linking with any C++ objects.
497 - Avoid SCons hanging when a piped command has a lot of output to read.
499 - Add QT support for preprocessing .ui files into .c files.
503 RELEASE 0.90 - Wed, 25 Jun 2003 14:24:52 -0500

513 - Fix handling of library prefixes when the subdirectory matches
516 From Timothee Bessett:
522 - Use '.lnk' as the suffix on the temporary file for linking long
523 command lines (necessary for the Phar Lap linkloc linker).
525 - Save non-string Options values as their actual type.
527 - Save Options string values that contain a single quote correctly.
529 - Save any Options values that are changed from the default
530 Environment values, not just ones changed on the command line or in
533 - Make closing the Options file descriptor exception-safe.
537 - SCons now enforces (with an error) that construction variables
538 must have the same form as valid Python identifiers.
540 - Fix man page bugs: remove duplicate AddPostAction() description;
541 document no_import_lib; mention that CPPFLAGS does not contain
542 $_CPPINCFLAGS; mention that F77FLAGS does not contain $_F77INCFLAGS;
543 mention that LINKFLAGS and SHLINKFLAGS contains neither $_LIBFLAGS
546 - Eliminate a dependency on the distutils.fancy_getopt module by
547 copying and pasting its wrap_text() function directly.
549 - Make the Script.Options() subclass match the underlying base class
552 - When reporting a target is up to date, quote the target like make
553 (backquote-quote) instead of with double quotes.
555 - Fix handling of ../* targets when using -U, -D or -u.
559 - Don't update the .sconsign files when run with -n.

584 to avoid getting fooled by leftover junk in the registry.
586 - Add support for MSVC++ .NET.
588 - Add support for MS Visual Studio project files (DSP, DSW,
589 SLN and VCPROJ files).
591 From Christoph Wiedemann

597 RELEASE 0.14 - Wed, 21 May 2003 05:16:32 -0500
601 - Use .dll (not .so) for shared libraries on Cygwin; use -fPIC
604 - Use 'rm' to remove files under Cygwin.
606 - Add a PLATFORM variable to construction environments.
608 - Remove the "platform" argument from tool specifications.
610 - Propogate PYTHONPATH when running the regression tests so distutils
611 can be found in non-standard locations.
613 - Using MSVC long command-line linking when running Cygwin.
615 - Portability fixes for a lot of tests.
617 - Add a Value Node class for dependencies on in-core Python values.

626 - Add an optional sort function argument to the GenerateHelpText()
629 - Evaluate the "varlist" variables when computing the signature of a
634 - Parse the source .java files for class names (including inner class
635 names) to figure out the target .class files that will be created.
637 - Make Java support work with Repositories and SConscriptChdir(0).
639 - Pass Nodes, not strings, to Builder emitter functions.

642 so we can use real Node attributes.
646 - Add Java support (javac, javah, jar and rmic).

653 - Check out CVS source files using POSIX path names (forward slashes
654 as separators) even on Win32.
656 - Add Node.clear() and Node.FS.Entry.clear() methods to wipe out a
657 Node's state, allowing it to be re-evaluated by continuous
658 integration build interfaces.
660 - Change the name of the Set{Build,Content}SignatureType() functions
661 to {Target,Source}Signatures(). Deprecate the old names but support
662 them for backwards compatibility.
664 - Add internal SCons.Node.FS.{Dir,File}.Entry() methods.
666 - Interpolate the null string if an out-of-range subscript is used
667 for a construction variable.

673 of an action to eliminate redundant signature calculations.
675 - Eliminate redundant signature calculations for Nodes.
677 - Optimize out calling hasattr() before accessing attributes.
679 - Say "Cleaning targets" (not "Building...") when the -c option is
684 - Quote the "Entering directory" message like Make.
688 - Add support for using Ghostscript to convert Postscript to PDF files.

703 various command-line options from with an SConscript file.
705 - Deprecate the old SetJobs() and GetJobs() functions in favor of
706 using the new generic {Set,Get}Option() functions.
708 - Fix a number of tests that searched for a Fortran compiler using the
709 external PATH instead of what SCons would use.
711 - Fix the interaction of SideEffect() and BuildDir() so that (for
712 example) PDB files get put correctly in a BuildDir().
716 - Contribute the "Autoscons" code for Autoconf-like checking for
717 the existence of libraries, header files and the like.
719 - Have the Tool() function add the tool name to the $TOOLS
720 construction variable.

737 From Christoph Wiedemann:
739 - Integrate David Snopek's "Autoscons" code as the new SConf
740 configuration subsystem, including caching of values between
741 runs (using normal SCons dependency mechanisms), tests, and
746 RELEASE 0.13 - Mon, 31 Mar 2003 20:22:00 -0600
750 - Fix a bug when BuildDir(duplicate=0) is used and SConscript
751 files are called from within other SConscript files.
753 - Support (older) versions of Perforce which don't set the Windows
758 RELEASE 0.12 - Thu, 27 Mar 2003 23:52:09 -0600
762 - Added support for the Perforce source code management system.
764 - Fix str(Node.FS) so that it returns a path relative to the calling
765 SConscript file's directory, not the top-level directory.
767 - Added support for a separate src_dir argument to SConscript()
768 that allows explicit specification of where the source files
769 for an SConscript file can be found.
771 - Support more easily re-usable flavors of command generators by
772 calling callable variables when strings are expanded.
776 - Added an INSTALL construction variable that can be set to a function
777 to control how the Install() and InstallAs() Builders install files.
778 The default INSTALL function now copies, not links, files.
780 - Remove deprecated features: the "name" argument to Builder objects,
781 and the Environment.Update() method.
783 - Add an Environment.SourceCode() method to support fetching files
784 from source code systems. Add factory methods that create Builders
785 to support BitKeeper, CVS, RCS, and SCCS. Add support for fetching
786 files from RCS or SCCS transparently (like GNU Make).
788 - Make the internal to_String() function more efficient.
790 - Make the error message the same as other build errors when there's a
791 problem unlinking a target file in preparation for it being built.
793 - Make TARGET, TARGETS, SOURCE and SOURCES reserved variable names and
794 warn if the user tries to set them in a construction environment.
796 - Add support for Tar and Zip files.
798 - Better documentation of the different ways to export variables to a
799 subsidiary SConscript file. Fix documentation bugs in a tools
800 example, places that still assumed SCons split strings on white
803 - Support fetching arbitrary files from the TARGETS or SOURCES lists
804 (e.g. ${SOURCES[2]}) when calculating the build signature of a
807 - Don't silently swallow exceptions thrown by Scanners (or other
808 exceptions while finding a node's dependent children).
810 - Push files to CacheDir() before calling the superclass built()
811 method (which may clear the build signature as part of clearing
812 cached implicit dependencies, if the file has a source scanner).
813 (Bug reported by Jeff Petkau.)
815 - Raise an internal error if we attempt to push a file to CacheDir()
816 with a build signature of None.
818 - Add an explicit Exit() function for terminating early.
820 - Change the documentation to correctly describe that the -f option
821 doesn't change to the directory in which the specified file lives.
823 - Support changing directories locally with SConscript directory
824 path names relative to any SConstruct file specified with -f.
825 This allows you to build in another directory by simply changing
826 there and pointing at the SConstruct file in another directory.
828 - Change the default SConscriptChdir() behavior to change to the
829 SConscript directory while it's being read.
831 - Fix an exception thrown when the -U option was used with no
832 Default() target specified.
834 - Fix -u so that it builds things in corresponding build directories
835 when used in a source directory.
839 - Add SharedObject() support to the masm tool.
841 - Fix WhereIs() to return normalized paths.
845 - Don't copy a built file to a CacheDir() if it's already there.
847 - Avoid partial copies of built files in a CacheDir() by copying
848 to a temporary file and renaming.
852 - Fix incorrect dependency-cycle errors when an Aliased source doesn't
857 RELEASE 0.11 - Tue, 11 Feb 2003 05:24:33 -0600
861 - Add support for IRIX and the SGI MIPSPro tool chain.
863 - Support using the MSVC tool chain when running Cygwin Python.
867 - Avoid losing signal bits in the exit status from a command,
868 helping terminate builds on interrupt (CTRL+C).
872 - Added new AddPreAction() and AddPostAction() functions that support
873 taking additional actions before or after building specific targets.
875 - Add support for the PharLap ETS tool chain.
879 - Allow Python function Actions to specify a list of construction
880 variables that should be included in the Action's signature.
882 - Allow libraries in the LIBS variable to explicitly include the prefix
883 and suffix, even when using the GNU linker.
884 (Bug reported by Neal Becker.)
886 - Use DOS-standard CR-LF line endings in the scons.bat file.
887 (Bug reported by Gary Ruben.)
889 - Doc changes: Eliminate description of deprecated "name" keyword
890 argument from Builder definition (reported by Gary Ruben).
892 - Support using env.Append() on BUILDERS (and other dictionaries).
893 (Bug reported by Bj=F6rn Bylander.)
895 - Setting the BUILDERS construction variable now properly clears
896 the previous Builder attributes from the construction Environment.
897 (Bug reported by Bj=F6rn Bylander.)
899 - Fix adding a prefix to a file when the target isn't specified.
900 (Bug reported by Esa Ilari Vuokko.)
902 - Clean up error messages from problems duplicating into read-only
903 BuildDir directories or into read-only files.
905 - Add a CommandAction.strfunction() method, and add an "env" argument
906 to the FunctionAction.strfunction() method, so that all Action
907 objects have strfunction() methods, and the functions for building
908 and returning a string both take the same arguments.
910 - Add support for new CacheDir() functionality to share derived files
911 between builds, with related options --cache-disable, --cache-force,
914 - Change the default behavior when no targets are specified to build
915 everything in the current directory and below (like Make). This
916 can be disabled by specifying Default(None) in an SConscript.
918 - Revamp SCons installation to fix a case-sensitive installation
919 on Win32 systems, and to add SCons-specific --standard-lib,
920 --standalone-lib, and --version-lib options for easier user
921 control of where the libraries get installed.
923 - Fix the ability to directly import and use Platform and Tool modules
924 that have been implicitly imported into an Environment().
926 - Add support for allowing an embedding interface to annotate a node
929 - Extend the SConscript() function to accept build_dir and duplicate
930 keyword arguments that function like a BuildDir() call.
934 - Fix the output of -c -n when directories are involved, so it
939 - Use a different shared object suffix (.os) when using gcc so shared
940 and static objects can exist side-by-side in the same directory.
942 - Allow the same object files on Win32 to be linked into either
943 shared or static libraries.
945 - Cache implicit cache values when using --implicit-cache.
949 RELEASE 0.10 - Thu, 16 Jan 2003 04:11:46 -0600
951 From Derrick 'dman' Hudson:
953 - Support Repositories on other file systems by symlinking or
954 copying files when hard linking won't work.
958 - Remove Python bytecode (*.pyc) files from the scons-local packages.
960 - Have FunctionActions print a description of what they're doing
961 (a representation of the Python call).
963 - Fix the Install() method so that, like other actions, it prints
964 what would have happened when the -n option is used.
966 - Don't create duplicate source files in a BuildDir when the -n
969 - Refactor the Scanner interface to eliminate unnecessary Scanner
970 calls and make it easier to write efficient scanners.
972 - Added a "recursive" flag to Scanner creation that specifies the
973 Scanner should be invoked recursively on dependency files returned
976 - Significant performance improvement from using a more efficient
977 check, throughout the code, for whether a Node has a Builder.
979 - Fix specifying only the source file to MultiStepBuilders such as
980 the Program Builder. (Bug reported by Dean Bair.)
982 - Fix an exception when building from a file with the same basename as
983 the subdirectory in which it lives. (Bug reported by Gerard Patel.)
985 - Fix automatic deduction of a target file name when there are
986 multiple source files specified; the target is now deduced from just
987 the first source file in the list.
989 - Documentation fixes: better initial explanation of SConscript files;
990 fix a misformatted "table" in the StaticObject explanation.
992 From Steven Knight and Steve Leblanc:
994 - Fix the -c option so it will remove symlinks.
998 - Add a Clean() method to support removing user-specified targets
999 when using the -c option.
1001 - Add a development script for running SCons through PyChecker.
1003 - Clean up things found by PyChecker (mostly unnecessary imports).
1005 - Add a script to use HappyDoc to create HTML class documentation.
1009 - Make the Environment.get() method return None by default.
1013 - Add SetJobs() and GetJobs() methods to allow configuration of the
1014 number of default jobs (still overridden by -j).
1016 - Convert the .sconsign file format from ASCII to a pickled Python
1019 - Error message cleanups: Made consistent the format of error
1020 messages (now all start with "scons: ***") and warning messages (now
1021 all start with "scons: warning:"). Caught more cases with the "Do
1022 not know how to build" error message.
1024 - Added support for the MinGW tool chain.
1026 - Added a --debug=includes option.
1030 RELEASE 0.09 - Thu, 5 Dec 2002 04:48:25 -0600
1034 - Add a Prepend() method to Environments, to append values to
1035 the beginning of construction variables.
1039 - Add long command-line support to the "lib" Tool (Microsoft library
1044 - Allow $$ in a string to be passed through as $.
1046 - Support file names with odd characters in them.
1048 - Add support for construction variable substition on scanner
1049 directories (in CPPPATH, F77PATH, LIBPATH, etc.).
1051 From Charles Crain and Steven Knight:
1053 - Add Repository() functionality, including the -Y option.
1057 - Fix auto-deduction of target names so that deduced targets end
1058 up in the same subdirectory as the source.
1060 - Don't remove source files specified on the command line!
1062 - Suport the Intel Fortran Compiler (ifl.exe).
1064 - Supply an error message if there are no command-line or
1065 Default() targets specified.
1067 - Fix the ASPPCOM values for the GNU assembler.
1068 (Bug reported by Brett Polivka.)
1070 - Fix an exception thrown when a Default() directory was specified
1071 when using the -U option.
1073 - Issue a warning when -c can't remove a target.
1075 - Eliminate unnecessary Scanner calls by checking for the
1076 existence of a file before scanning it. (This adds a generic
1077 hook to check an arbitrary condition before scanning.)
1079 - Add explicit messages to tell when we're "Reading SConscript files
1080 ...," "done reading SConscript files," "Building targets," and
1081 "done building targets." Add a -Q option to supress these.
1083 - Add separate $SHOBJPREFIX and $SHOBJSUFFIX construction variables
1084 (by default, the same as $OBJPREFIX and $OBJSUFFIX).
1086 - Add Make-like error messages when asked to build a source file,
1087 and before trying to build a file that doesn't have all its source
1088 files (including when an invalid drive letter is used on WIN32).
1090 - Add an scons-local-{version} package (in both .tar.gz and .zip
1091 flavors) to help people who want to ship SCons as a stand-alone
1092 build tool in their software packages.
1094 - Prevent SCons from unlinking files in certain situations when
1095 the -n option is used.
1097 - Change the name of Tool/lib.py to Tool/mslib.py.
1099 From Steven Knight and Anthony Roach:
1101 - Man page: document the fact that Builder calls return Node objects.
1105 - Refactor option processing to use our own version of Greg Ward's
1106 Optik module, modified to run under Python 1.5.2.
1108 - Add a ParseConfig() command to modify an environment based on
1109 parsing output from a *-config command.
1113 - Fix interpretation of '#/../foo' on Win32 systems.
1117 - Fixed use of command lines with spaces in their arguments,
1118 and use of Nodes with spaces in their string representation.
1120 - Make access and modification times of files in a BuildDir match
1121 the source file, even when hard linking isn't available.
1123 - Make -U be case insensitive on Win32 systems.
1125 - Issue a warning and continue when finding a corrupt .sconsign file.
1127 - Fix using an alias as a dependency of a target so that if one of the
1128 alias' dependencies gets rebuilt, the resulting target will, too.
1130 - Fix differently ordered targets causing unnecessary rebuilds
1131 on case insensitive systems.
1133 - Use os.system() to execute external commands whenever the "env"
1134 utility is available, which is much faster than fork()/exec(),
1135 and fixes the -j option on several platforms.
1137 - Fix use of -j with multiple targets.
1139 - Add an Options() object for friendlier accomodation of command-
1142 - Add support for Microsoft VC++ precompiled header (.pch) files,
1143 debugger (.pdb) files, and resource (.rc) files.
1145 - Don't compute the $_CPPINCFLAGS, $_F77INCFLAGS, $_LIBFLAGS and
1146 $_LIBDIRFLAGS variables each time a command is executed, define
1147 them so they're computed only as needed. Add a new _concat
1148 function to the Environment that allows people to define their
1149 own similar variables.
1151 - Fix dependency scans when $LIBS is overridden.
1153 - Add EnsurePythonVersion() and EnsureSConsVersion() functions.
1155 - Fix the overly-verbose stack trace on ListBuilder build errors.
1157 - Add a SetContentSignatureType() function, allowing use of file
1158 timestamps instead of MD5 signatures.
1160 - Make -U and Default('source') fail gracefully.
1162 - Allow the File() and Dir() methods to take a path-name string as
1163 the starting directory, in addition to a Dir object.
1165 - Allow the command handler to be selected via the SPAWN, SHELL
1166 and ESCAPE construction variables.
1168 - Allow construction variables to be overridden when a Builder
1173 - Dynamically check for the existence of utilities with which to
1174 initialize Environments by default.
1178 RELEASE 0.08 - Mon, 15 Jul 2002 12:08:51 -0500
1182 - Fixed a bug with relative CPPPATH dirs when using BuildDir().
1183 (Bug reported by Bob Summerwill.)
1185 - Added a warnings framework and a --warn option to enable or
1188 - Make the C scanner warn users if files referenced by #include
1189 directives cannot be found and --warn=dependency is specified.
1191 - The BUILDERS construction variable should now be a dictionary
1192 that maps builder names to actions. Existing uses of lists,
1193 and the Builder name= keyword argument, generate warnings
1194 about use of deprecated features.
1196 - Removed the "shared" keyword argument from the Object and
1199 - Added separated StaticObject, SharedObject, StaticLibrary and
1200 SharedLibrary builders. Made Object and Library synonyms for
1201 StaticObject and StaticLibrary, respectively.
1203 - Add LIBS and LIBPATH dependencies for shared libraries.
1205 - Removed support for the prefix, suffix and src_suffix arguments
1206 to Builder() to be callable functions.
1208 - Fix handling file names with multiple dots.
1210 - Allow a build directory to be outside of the SConstruct tree.
1212 - Add a FindFile() function that searches for a file node with a
1215 - Add $CPPFLAGS to the shared-object command lines for g++ and gcc.
1217 From Charles Crain and Steven Knight:
1219 - Add a "tools=" keyword argument to Environment instantiation,
1220 and a separate Tools() method, for more flexible specification
1221 of tool-specific environment changes.
1225 - Add a "platform=" keyword argument to Environment instantiation,
1226 and a separate Platform() method, for more flexible specification
1227 of platform-specific environment changes.
1229 - Updated README instructions and setup.py code to catch an
1230 installation failure from not having distutils installed.
1232 - Add descriptions to the -H help text for -D, -u and -U so
1233 people can tell them apart.
1235 - Remove the old feature of automatically splitting strings
1236 of file names on white space.
1238 - Add a dependency Scanner for native Fortran "include" statements,
1239 using a new "F77PATH" construction variable.
1241 - Fix C #include scanning to detect file names with characters like
1244 - Add more specific version / build output to the -v option.
1246 - Add support for the GNU as, Microsoft masm, and nasm assemblers.
1248 - Allow the "target" argument to a Builder call to be omitted, in
1249 which case the target(s) are deduced from the source file(s) and the
1250 Builder's specified suffix.
1252 - Add a tar archive builder.
1254 - Add preliminary support for the OS/2 Platform, including the icc
1259 - Fix --implicit-cache if the scanner returns an empty list.
1263 - Add a "multi" keyword argument to Builder creation that specifies
1264 it's okay to call the builder multiple times for a target.
1266 - Set a "multi" on Aliases so multiple calls will append to an Alias.
1268 - Fix emitter functions' use of path names when using BuildDir or
1271 - Fix --implicit-cache causing redundant rebuilds when the header
1274 - Fix --implicit-cache when a file has no implicit dependencies and
1275 its source is generated.
1277 - Make the drive letters on Windows always be the same case, so that
1278 changes in the case of drive letters don't cause a rebuild.
1280 - Fall back to importing the SCons.TimeStamp module if the SCons.MD5
1281 module can't be imported.
1283 - Fix interrupt handling to guarantee that a single interrupt will
1284 halt SCons both when using -j and not.
1286 - Fix .sconsign signature storage so that output files of one build
1287 can be safely used as input files to another build.
1289 - Added a --debug=time option to print SCons execution times.
1291 - Print an error message if a file can't be unlinked before being
1292 built, rather than just silently terminating the build.
1294 - Add a SideEffect() method that can be used to tell the build
1295 engine that a given file is created as a side effect of building
1296 a target. A file can be specified as a side effect of more than
1297 one build comand, in which case the commands will not be executed
1300 - Significant performance gains from not using our own version of
1301 the inefficient stock os.path.splitext() method, caching source
1302 suffix computation, code cleanup in MultiStepBuilder.__call__(),
1303 and replicating some logic in scons_subst().
1305 - Add --implicit-deps-changed and --implicit-deps-unchanged options.
1307 - Add a GetLaunchDir() function.
1309 - Add a SetBuildSignatureType() function.
1313 - Add an Append() method to Environments, to append values to
1314 construction variables.
1316 - Change the name of Update() to Replace(). Keep Update() as a
1317 deprecated synonym, at least for now.
1319 From Terrel Shumway:
1321 - Use a $PYTHON construction variable, initialized to sys.executable,
1322 when using Python to build parts of the SCons packages.
1324 - Use sys.prefix, not sys.exec_prefix, to find pdb.py.
1328 RELEASE 0.07 - Thu, 2 May 2002 13:37:16 -0500
1332 - Changes to build SCons packages on IRIX (and other *NIces).
1334 - Don't create a directory Node when a file already exists there,
1337 - Add 'dirs' and 'names' keyword arguments to SConscript for
1338 easier specification of subsidiary SConscript files.
1342 - Internal cleanup of environment passing to function Actions.
1344 - Builders can now take arbitrary keyword arguments to create
1345 attributes to be passed to: command generator functions,
1346 FunctionAction functions, Builder emitter functions (below),
1347 and prefix/suffix generator functions (below).
1349 - Command generator functions can now return ANYTHING that can be
1350 converted into an Action (a function, a string, a CommandGenerator
1351 instance, even an ActionBase instance).
1353 - Actions now call get_contents() with the actual target and source
1354 nodes used for the build.
1356 - A new DictCmdGenerator class replaces CompositeBuilder to support
1357 more flexible Builder behavior internally.
1359 - Builders can now take an emitter= keyword argument. An emitter
1360 is a function that takes target, source, and env argument, then
1361 return a 2-tuple of (new sources, new targets). The emitter is
1362 called when the Builder is __call__'ed, allowing a user to modify
1363 source and target lists.
1365 - The prefix, suffix and src_suffix Builder arguments now take a
1366 callable as well a string. The callable is passed the Environment
1367 and any extra Builder keyword arguments and is expected to return
1368 the appropriate prefix or suffix.
1370 - CommandActions can now be a string, a list of command + argument
1371 strings, or a list of commands (strings or lists).
1373 - Added shared library support. The Object and Library Builders now
1374 take a "shared=1" keyword argument to specify that a shared object
1375 or shared library should be built. It is an error to try to build
1376 static objects into a shared library or vice versa.
1378 - Win32 support for .def files has been added. Added the Win32-specific
1379 construction variables $WIN32DEFPREFIX, $WIN32DEFSUFFIX,
1380 $WIN32DLLPREFIX and $WIN32IMPLIBPREFIX. When building a .dll,
1381 the new construction variable $WIN32_INSERT_DEF, controls whether
1382 the appropriately-named .def file is inserted into the target
1383 list (if not already present). A .lib file is always added to
1384 a Library build if not present in the list of targets.
1386 - ListBuilder now passes all targets to the action, not just the first.
1388 - Fix so that -c now deletes generated yacc .h files.
1390 - Builder actions and emitter functions can now be initialized, through
1391 construction variables, to things other than strings.
1393 - Make top-relative '#/dir' lookups work like '#dir'.
1395 - Fix for relative CPPPATH directories in subsidiary SConscript files
1398 - Add a for_signature argument to command generators, so that
1399 generators that need to can return distinct values for the
1400 command signature and for executing the command.
1404 - Create a better scons.bat file from a py2bat.py script on the Python
1405 mailing list two years ago (modeled after pl2bat.pl).
1409 - Fix so that -c -n does *not* remove the targets!
1411 - Man page: Add a hierarchical libraries + Program example.
1413 - Support long MSVC linker command lines through a builder action
1414 that writes to a temporary file and uses the magic MSVC "link @file"
1415 argument syntax if the line is longer than 2K characters.
1417 - Fix F77 command-line options on Win32 (use /Fo instead of -o).
1419 - Use the same action to build from .c (lower case) and .C (upper
1420 case) files on case-insensitive systems like Win32.
1422 - Support building a PDF file directly from a TeX or LaTeX file
1423 using pdftex or pdflatex.
1425 - Add a -x option to runtest.py to specify the script being tested.
1426 A -X option indicates it's an executable, not a script to feed
1427 to the Python interpreter.
1429 - Add a Split() function (identical to SCons.Util.argmunge()) for use
1430 in the next release, when Builders will no longer automatically split
1431 strings on white space.
1435 - Add the SConscriptChdir() method.
1439 - Fix --debug=tree when used with directory targets.
1441 - Significant internal restructuring of Scanners and Taskmaster.
1443 - Added new --debug=dtree option.
1445 - Fixes for --profile option.
1447 - Performance improvement in construction variable substitution.
1449 - Implemented caching of content signatures, plus added --max-drift
1450 option to control caching.
1452 - Implemented caching of dependency signatures, enabled by new
1453 --implicit-cache option.
1455 - Added abspath construction variable modifier.
1457 - Added $SOURCE variable as a synonym for $SOURCES[0].
1459 - Write out .sconsign files on error or interrupt so intermediate
1460 build results are saved.
1462 - Change the -U option to -D. Make a new -U that builds just the
1463 targets from the local SConscript file.
1465 - Fixed use of sys.path so Python modules can be imported from
1466 the SConscript directory.
1468 - Fix for using Aliases with the -u, -U and -D options.
1470 - Fix so that Nodes can be passed to SConscript files.
1474 - Changes for official Debian packaging.
1478 RELEASE 0.06 - Thu, 28 Mar 2002 01:24:29 -0600
1482 - Fix command generators to expand construction variables.
1484 - Make FunctionAction arguments be Nodes, not strings.
1486 From Stephen Kennedy:
1488 - Performance: Use a dictionary, not a list, for a Node's parents.
1492 - Add .zip files to the packages we build.
1494 - Man page: document LIBS, fix a typo, document ARGUMENTS.
1496 - Added RANLIB and RANLIBFLAGS construction variables. Only use them
1497 in ARCOM if there's a "ranlib" program on the system.
1499 - Add a configurable CFILESUFFIX for the Builder of .l and .y files
1502 - Add a CXXFile Builder that turns .ll and .yy files into .cc files
1503 (configurable via a CXXFILESUFFIX construction variable).
1505 - Use the POSIX-standard lex -t flag, not the GNU-specific -o flag.
1506 (Bug reported by Russell Christensen.)
1508 - Fixed an exception when CPPPATH or LIBPATH is a null string.
1509 (Bug reported by Richard Kiss.)
1511 - Add a --profile=FILE option to make profiling SCons easier.
1513 - Modify the new DVI builder to create .dvi files from LaTeX (.ltx
1516 - Add support for Aliases (phony targets).
1518 - Add a WhereIs() method for searching for path names to executables.
1520 - Add PDF and PostScript document builders.
1522 - Add support for compiling Fortran programs from a variety of
1523 suffixes (a la GNU Make): .f, .F, .for, .FOR, .fpp and .FPP
1525 - Support a CPPFLAGS variable on all default commands that use the
1530 - Add support for the -U option.
1532 - Allow CPPPATH, LIBPATH and LIBS to be specified as white-space
1535 - Add a document builder to create .dvi files from TeX (.tex) files.
1539 - Fix: Construction variables with values of 0 were incorrectly
1542 - Support env['VAR'] to fetch construction variable values.
1544 - Man page: document Precious().
1548 RELEASE 0.05 - Thu, 21 Feb 2002 16:50:03 -0600
1552 - Set PROGSUFFIX to .exe under Cygwin.
1556 - Allow a library to specified as a command-line source file, not just
1557 in the LIBS construction variable.
1559 - Compensate for a bug in os.path.normpath() that returns '' for './'
1562 - More performance optimizations: cache #include lines from files,
1563 eliminate unnecessary calls.
1565 - If a prefix or suffix contains white space, treat the resulting
1566 concatenation as separate arguments.
1568 - Fix irregularities in the way we fetch DevStudio information from
1569 the Windows registry, and in our registry error handling.
1573 - Flush stdout after print so it intermixes correctly with stderr
1576 - Allow Scanners to return a list of strings, and document how to
1577 write your own Scanners.
1579 - Look up implicit (scanned) dependencies relative to the directory
1580 of file being scanned.
1582 - Make writing .sconsign files more robust by first trying to write
1583 to a temp file that gets renamed.
1585 - Create all of the directories for a list of targets before trying
1586 to build any of the targets.
1588 - WIN32 portability fixes in tests.
1590 - Allow the list of variables exported to an SConscript file to be
1593 - Document the overlooked LIBPATH construction variable.
1594 (Bug reported by Eicke Godehardt.)
1596 - Fix so that Ignore() ignores indirect, implicit dependencies
1597 (included files), not just direct dependencies.
1599 - Put the man page in the Debian distribution.
1601 - Run HTML docs through tidy to clean up the HTML (for Konqueror).
1603 - Add preliminary support for Unicode strings.
1605 - Efficiency: don't scan dependencies more than once during the
1608 - Fix the -c option so it doesn't stop removing targets if one doesn't
1610 (Bug reported by Paul Connell.)
1612 - Fix the --debug=pdb option when run on Windows NT.
1613 (Bug reported by Paul Connell.)
1615 - Add support for the -q option.
1619 - Add support for the -u option.
1621 - Add .cc and .hh file suffixes to the C Scanner.

1631 RELEASE 0.04 - Wed, 30 Jan 2002 11:09:42 -0600
1635 - Significant performance improvements in the Node.FS and
1638 - Fix signatures of binary files on Win32 systems.
1640 - Allow LIBS and LIBPATH to be strings, not just arrays.
1642 - Print a traceback if a Python-function builder throws an exception.
1646 - Fix using a directory as a Default(), and allow Default() to
1647 support white space in file names for strings in arrays.
1649 - Man page updates: corrected some mistakes, documented various
1650 missing Environment methods, alphabetized the construction
1651 variables and other functions, defined begin and end macros for
1652 the example sections, regularized white space separation, fixed
1653 the use of Export() in the Multiple Variants example.
1655 - Function action fixes: None is now a successful return value.
1656 Exceptions are now reported. Document function actions.
1658 - Add 'Action' and 'Scanner' to the global keywords so SConscript
1659 files can use them too.
1661 - Removed the Wrapper class between Nodes and Walkers.
1663 - Add examples using Library, LIBS, and LIBPATH.
1665 - The C Scanner now always returns a sorted list of dependencies
1666 so order changes don't cause unnecessary rebuilds.
1668 - Strip $(-$) bracketed text from command lines. Use this to
1669 surround $_INCDIRS and $_LIBDIRS so we don't rebuild in response
1670 to changes to -I or -L options.
1672 - Add the Ignore() method to ignore dependencies.
1674 - Provide an error message when a nonexistent target is specified
1675 on the command line.
1677 - Remove targets before building them, and add an Environment
1678 Precious() method to override that.
1680 - Eliminate redundant calls to the same builder when the target is a
1681 list of targets: Add a ListBuilder class that wraps Builders to
1682 handle lists atomically. Extend the Task class to support building
1683 and updating multiple targets in a single Task. Simplify the
1684 interface between Task and Taskmaster.
1686 - Add a --debug=pdb option to re-run SCons under the Python debugger.
1688 - Only compute a build signature once for each node.
1690 - Changes to our sys.path[] manipulation to support installation into
1691 an arbitrary --prefix value.
1695 - Add var=value command-line arguments.
1699 RELEASE 0.03 - Fri, 11 Jan 2002 01:09:30 -0600
1703 - Performance improvements in the Node.FS and Sig.Calculator classes.
1705 - Add the InstallAs() method.
1707 - Execute commands through an external interpreter (sh, cmd.exe, or
1708 command.com) to handle redirection metacharacters.
1710 - Allow the user to supply a command handler.
1714 - Search both /usr/lib and /usr/local/lib for scons directories by
1715 adding them both to sys.path, with whichever is in sys.prefix first.
1717 - Fix interpreting strings of multiple white-space separated file names
1718 as separate file names, allowing prefixes and suffixes to be appended
1719 to each individually.
1721 - Refactor to move CompositeBuilder initialization logic from the
1722 factory wrapper to the __init__() method, and allow a Builder to
1723 have both an action and a src_builder (or array of them).
1725 - Refactor BuilderBase.__call__() to separate Node creation/lookup
1726 from initialization of the Node's builder information.
1728 - Add a CFile Builder object that supports turning lex (.l) and
1729 yacc (.y) files into .c files.
1731 - Document: variable interpretation attributes; how to propogate
1732 the user's environment variables to executed commands; how to
1733 build variants in multiple BuildDirs.
1735 - Collect String, Dict, and List type-checking in common utility
1736 routines so we can accept User{String,Dict,List}s all over.
1738 - Put the Action factory and classes into their own module.
1740 - Use one CPlusPlusAction in the Object Builder's action dictionary,
1741 instead of letting it create multiple identical instances.
1743 - Document the Install() and InstallAs() methods.
1747 - Require that a Builder be given a name argument, supplying a
1748 useful error message when it isn't.
1752 - Add a "duplicate" keyword argument to BuildDir() that can be set
1753 to prevent linking/copying source files into build directories.
1755 - Add a "--debug=tree" option to print an ASCII dependency tree.
1757 - Fetch the location of the Microsoft Visual C++ compiler(s) from
1758 the Registry, instead of hard-coding the location.
1760 - Made Scanner objects take Nodes, not path names.
1762 - Have the C Scanner cache the #include file names instead of
1763 (re-)scanning the file each time it's called.
1765 - Created a separate class for parent "nodes" of file system roots,
1766 eliminating the need for separate is-parent-null checks everywhere.
1768 - Removed defined __hash__() and __cmp() methods from FS.Entry, in
1769 favor of Python's more efficient built-in identity comparisons.
1773 RELEASE 0.02 - Sun, 23 Dec 2001 19:05:09 -0600
1777 - Added the Install(), BuildDir(), and Export() methods.
1779 - Fix the -C option by delaying setting the top of the FS tree.
1781 - Avoid putting the directory path on the libraries in the LIBS
1782 construction variable.
1784 - Added a GetBuildPath() method to return the full path to the
1785 Node for a specified string.
1787 - Fixed variable substitution in CPPPATH and LIBPATH.
1791 - Fixed the version comment in the scons.bat (the UNIX geek used
1794 - Fix to setup.py so it doesn't require a sys.argv[1] argument.
1796 - Provide make-like warning message for "command not found" and
1799 - Added an EXAMPLES section to the man page.
1801 - Make Default() targets properly relative to their SConscript
1802 file's subdirectory.
1806 - Documented CXXFLAGS, CXXCOM, and CPPPATH.
1808 - Fixed SCONS_LIB_DIR to work as documented.
1810 - Made Default() accept Nodes as arguments.
1812 - Changed Export() to make it easier to use.
1814 - Added the Import() and Return() methods.
