cheatmake - fool make into not rebuilding certain files

cheatmake was written by David Faure <faure@kde.org>. This manual page was prepared by Ben Burton
       <bab@debian.org> for the Debian GNU/Linux® system (but may be used by others).

[FIXME: source]                                    2003-03-08                                       CHEATMAKE(1)

cheatmake is used to save time when recompiling. It can fool make into skipping files that haven't
       changed in a meaningful way. This can be used for instance when you change a comment in a file but none
       of the actual code.

       This utility is part of the KDE Software Development Kit.

       One of the following variables (but not both) should be set if the source directory is different from the
       build directory. If the build directory is simply a subdirectory of the source directory, the simpler
       variable OBJ_SUBDIR should be used.

       OBJ_SUBJDIR
           Indicates that the build directory is in the given subdirectory of the source directory. For
           instance, if the source directory is kdesdk and the build directory is kdesdk/obj-i386-linux, then
           OBJ_SUBDIR should be set to obj-i386-linux.

       OBJ_REPLACEMENT
           A sed expression that is used to transform the source directory into the build directory. For
           instance, if the source directory is kdesdk/obj-i386-linux, then OBJ_REPLACEMENT should be set to
           s#kdesdk#kdesdk-obj#.
