NAME
       File::ShouldUpdate - should files be rebuilt?

VERSION
       version 0.2.1

SYNOPSIS
           use File::ShouldUpdate qw/ should_update should_update_multi /;

           if (should_update("output.html", ":", "in.tt2", "data.sqlite"))
           {
               system("./my-gen-html");
           }

           if (should_update_multi(["output.html", "about.html", "contact.html"], ":", ["in.tt2", "data.sqlite"]))
           {
               system("./my-gen-html-multi");
           }

DESCRIPTION
       This module provides should_update() and should_update_multi() which
       can be used to determine if files should be updated based on the mtime
       timestamps of their dependencies. They avoid confusing between targets
       and dependencies by using the syntactic sugar of the familiar makefile
       rules ( <https://en.wikipedia.org/wiki/Make_(software)> ).

FUNCTIONS
   my $verdict = should_update($target, ":", @deps);
       Should $target be updated if it doesn't exist or older than any of the
       deps.

   my $verdict = should_update_multi([@targets], ":", [@deps]);
       Should @targets be updated if some of them do not exist or any of them
       are older than any of the deps.

       Note that you must pass array references.

       [Added in version 0.2.0.]
