module for extracting prerequisites from Perl code

 Perl::PrereqScanner is a Perl module that extracts distribution prerequisites
 from files through various means. The extraction is not perfect but provides
 a best-guess approximation, currently detecting the following:
 .
   * plain lines beginning with use or require in perl modules and scripts
   * regular inheritance declared with the base and parent pragmata
   * Moose inheritance declared with the extends keyword
   * Moose roles included with the with keyword
