NAME

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

VERSION

       version 0.008

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

       This library should run on perls released even a long time ago.  It should work on any version of perl
       released in the last five years.

       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.
