dnl shellfuncs.m4 ... phew, a really nice m4 file containing shellfunction defs
2
dnl for several shell functions that I wanted to be
3
dnl concentrated on one point rather than spilling it over
6
dnl is needed since most of the shellcode deals with '

dnl now write a generic header - for all files using this shellfunc (lib)
