Dist::Zilla::Plugin::Prereqs::Recommend::MatchInstalled The "[Prereqs::Recommend::MatchInstalled]" is a tool for authors who wish to keep end users informed of which versions of critical dependencies the author has themselves used, as an encouragement for the users to consume at least that version, but without making it a hard requirement. In practice this can be used for anything, but this modules author currently recommends you restrict this approach only to development dependencies, *mostly* because even a system of auto-recommendation is still too aggressive for most modules, or if you insist this concept on "CPAN", use something with "but not larger than" mechanics like "[Prereqs::Upgrade]" 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) 2017 by Kent Fredric .
