5 SCons - a software construction tool
15 - Performance improvements in the Node.FS and Sig.Calculator classes.
17 - Add the InstallAs() method.
21 - Search both /usr/lib and /usr/local/lib for scons directories by
22 adding them both to sys.path, with whichever is in sys.prefix first.
24 - Fix interpreting strings of multiple white-space separated file names
25 as separate file names, allowing prefixes and suffixes to be appended
28 - Refactor to move CompositeBuilder initialization logic from the
29 factory wrapper to the __init__() method, and allow a Builder to
30 have both an action and a src_builder (or array of them).
32 - Refactor BuilderBase.__call__() to separate Node creation/lookup
33 from initialization of the Node's builder information.
35 - Add a CFile Builder object that supports turning lex (.l) and
36 yacc (.y) files into .c files.
38 - Document: variable interpretation attributes; how to propogate
39 the user's environment variables to executed commands; how to
40 build variants in multiple BuildDirs.
42 - Collect String, Dict, and List type-checking in common utility
43 routines so we can accept User{String,Dict,List}s all over.
45 - Put the Action factory and classes into their own module.
47 - Use one CPlusPlusAction in the Object Builder's action dictionary,
48 instead of letting it create multiple identical instances.
50 - Document the Install() and InstallAs() methods.
54 - Require that a Builder be given a name argument, supplying a
55 useful error message when it isn't.
59 - Add a "duplicate" keyword argument to BuildDir() that can be set
60 to prevent linking/copying source files into build directories.
62 - Add a "--debug=tree" option to print an ASCII dependency tree.
64 - Fetch the location of the Microsoft Visual C++ compiler(s) from
65 the Registry, instead of hard-coding the location.
67 - Made Scanner objects take Nodes, not path names.
69 - Have the C Scanner cache the #include file names instead of
70 (re-)scanning the file each time it's called.
72 - Created a separate class for parent "nodes" of file system roots,
73 eliminating the need for separate is-parent-null checks everywhere.
75 - Removed defined __hash__() and __cmp() methods from FS.Entry, in
76 favor of Python's more efficient built-in identity comparisons.
80 RELEASE 0.02 - Sun, 23 Dec 2001 19:05:09 -0600
84 - Added the Install(), BuildDir(), and Export() methods.
86 - Fix the -C option by delaying setting the top of the FS tree.
88 - Avoid putting the directory path on the libraries in the LIBS
89 construction variable.
91 - Added a GetBuildPath() method to return the full path to the
92 Node for a specified string.
94 - Fixed variable substitution in CPPPATH and LIBPATH.
98 - Fixed the version comment in the scons.bat (the UNIX geek used
101 - Fix to setup.py so it doesn't require a sys.argv[1] argument.
103 - Provide make-like warning message for "command not found" and
106 - Added an EXAMPLES section to the man page.
108 - Make Default() targets properly relative to their SConscript
113 - Documented CXXFLAGS, CXXCOM, and CPPPATH.
115 - Fixed SCONS_LIB_DIR to work as documented.
117 - Made Default() accept Nodes as arguments.
119 - Changed Export() to make it easier to use.
121 - Added the Import() and Return() methods.
