The command line used to call the lexical analyzer generator
to generate a source file.
+.IP LEXCOMSTR
+The string displayed when generating a source file
+using the lexical analyzer generator.
+If this is not set, then $LEXCOM (the command line) is displayed.

.IP _LIBDIRFLAGS
An automatically-generated construction variable
containing the linker command-line options
The command line used to call the parser generator
to generate a source file.
+.IP YACCCOMSTR
+The string displayed when generating a source file
+using the parser generator.
+If this is not set, then $YACCCOM (the command line) is displayed.

.IP YACCFLAGS
General options passed to the parser generator.
If $YACCFLAGS contains a \-d option,
source file names.
- Support easier configurability of what's displayed by various default
- actions through new construction variables: $ASCOMSTR, $CCCOMSTR,
- $CXXCOMSTR, $LINKCOMSTR, $SHCCCOMSTR and $SHCXXCOMSTR, $SHLINKCOMSTR.
