NAME

       App::Whiff - find the first executable of a series of alternatives

VERSION

       version 0.005

DESCRIPTION

       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 executable.

METHODS

   find_first
         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.

   run
       This method is called by the whiff program to ... well, run.
