\The one I know of would be a problem on non-BSD systems if they have the
\following features:
\
\	1) "#!" - the ability for the kernel to recognize that an
\	   executable file is really a shell (or other) script, and to run
\	   the appropriate shell on it
\
\	2) symbolic links (not necessary in all cases, but necessary to
\	   make it work under arbitrary circumstances)

I don't need 2 at all! Just a bit patience will do...
