And there are environments where it's worth minimising the overhead of
system processes, even while you're accessing the file system in
search of external tools! But if this is its primary selling point
then maybe it should be mentioned in the package description:
Description: Perl module for searching paths for executable programs
File::Which simulates the behavior of the standard 'which' program: it
searches directories of a user's PATH (as returned by File::Spec)
looking for executable files matching a given name.
.
On Debian /usr/bin/which is guaranteed to be available, but going
through the Perl implementation can still save a fork.
