The Perl 5 module MooseX::App::Cmd marries App::Cmd with MooseX::Getopt. Use it like App::Cmd advises (especially see App::Cmd::Tutorial), swapping App::Cmd::Command for MooseX::App::Cmd::Command. Then you can write your moose commands as moose classes, with MooseX::Getopt defining the options for you instead of opt_spec returning a Getopt::Long::Descriptive spec.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
Problem reports, updates or suggestions for this package should be reported with send-pr.
