NAME

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

VERSION

       version 0.006

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.

PERL VERSION SUPPORT

       This module has a long-term perl support period.  That means it will not require a version
       of perl released fewer than five years ago.

       Although it may work on older versions of perl, no guarantee is made that the minimum
       required version will not be increased.  The version may be increased for any reason, and
       there is no promise that patches will be accepted to lower the minimum required perl.

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.
