App::Whiff - find the first executable of a series of alternatives
This module implements logic used by the whiff
command, which takes a
number of command names and returns the first one that exists and is
my $filename = App::Whiff->find_first(\@names);
Given an arrayref of command names (which should not
be anything other
than base filename), this method either returns an absolute path to the first
of the alternatives found in the path (using File::Which) or false.
This method is called by the whiff
program to ... well, run.
