Okay. I think I like your proposed find_tool slightly better than a
bunch of separate require_* functions and it sounds doable. It should
probably be dependant on Which (maybe=; while test -n "$1" && test ":"
!= $1; do maybes="$maybes `Which -a $1`"; shift; done; test -n "$1" &&
shift; for trytool in $maybes; do ...). Also, if it can do real
tests, the version_test is actually counter-productive, I think.

Cheers,

Derek
