Devel::Isa::Explainer This module is a simple tool for quickly visualizing inheritance hierarchies to quickly see what subs are available for a given package, or to ascertain where a given sub you might see in use is coming from. This module does not concern itself with any of the fanciness of Roles, and instead, relies entirely on standard Perl5 Object Model infrastructure. ( Roles are effectively invisible at run-time as they appear as composed subs in the corresponding class ) INSTALLATION This is a Perl module distribution. It should be installed with whichever tool you use to manage your installation of Perl, e.g. any of cpanm . cpan . cpanp -i . Consult http://www.cpan.org/modules/INSTALL.html for further instruction. Should you wish to install this module manually, the procedure is perl Makefile.PL make make test make install COPYRIGHT AND LICENSE This software is copyright (c) 2016 by Kent Fredric <firstname.lastname@example.org>.
