This is my directory of hacks on Jam.
compile_with_SUB_rule.c
A version of compile.c with a SUB rule (akin to sed's s//).
Lightly tested. Here in case I'll ever need it.
hdrscan_cache/...
Modifications to Craig McPheeters' header scan code. He has
incorporated the changes (or, at least, the spirit of them) and I
now use his version again.
hdrscan_on_target_fix/...
nt_msvcdir_fix/...
Bug fixes. See the change descriptions in each directory.
jamshell/...
A stpuid shell for Win32.
patched_version/...
A custom patched version of Jam with all of the above changes and
more. See patched_version/LOCAL_CHANGES.txt.
