cryp.to ac-archive's Miscellaneous (released)

look into subdirs and copy the (real) files that match pattern into the local directory. Preferably we use a symbolic link of course. existing local files are not overwritten.

the default casepattern is "*.?|*.cc|*.cpp" the default subdir-list contains all subdirs available

(requires AC_PROG_CP_S)
