Getopt::Long is a standard Perl5 (core) module, but maintained separately.
Note that this source tree contains a Makefile.PL (for Perl) and a GNUmakefile (for development).
Relevant targets of the GNUmakefile are
-
test : runs the standard tests
-
regtest : runs the extended regression tests
-
dist : creates a new tar.gz distribution
Note that a Github release is a snapshot of this repository. An official CPAN release must be made with the 'dist' target of the GNUmakefile.
