Moos completes the M to Moose sequence of Perl OO modules. This one is pure Perl, single file and mostly Moose compatible(for what it does). Moos has no non-core dependencies, but certain features (roles, debugging functions, legacy Perl support) do require additional modules. If you steer away from those features, you don't need those additional modules.
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.
