Project:Perl/How to version-bump dev-perl

Here's a recipe for version-bumping dev-perl packages, with reasonable time expenditure. Please improve.

Who's doing what
In 2015:
 * zlogene: dev-perl/[A-F].*
 * dilfridge: dev-perl/[G-L].*
 * civil: dev-perl/[M-R].*
 * monsieurp: dev-perl/[S-Z].*

Preparations
dev-perl/CGI dev-perl/File-ShareDir-Install dev-perl/Module-Build-Tiny dev-perl/Test-Base dev-perl/Test-Differences dev-perl/Test-Exception dev-perl/Test-Fatal dev-perl/Test-MockObject dev-perl/Test-NoWarnings dev-perl/Test-Pod dev-perl/Test-Requires dev-perl/Test-Warn dev-perl/Test-Warnings to do: which ones?
 * Add typical dependencies to your installation (i.e., world)
 * If you're on stable, update some dev-perl packages to ~arch
 * enable tests for perl-core, dev-perl, and dev-lang/perl:


 * Open the following tabs in a browser of your choice:
 * Euscan page for the dev-perl category
 * CPAN search

Bumping a package

 * Pick a package to be bumped, say dev-perl/foo-bar
 * Search on CPAN for it (foo::bar), and open the corresponding page of the latest version, say 1.05
 * Copy latest existing ebuild version to new version, i.e. foo-bar-1.50.0.ebuild (use gentoo-modperl-version.pl if you're not sure about the conversion)
 * ekeyword ~all foo-bar-1.50.0.ebuild
 * Open foo-bar-1.50.0.ebuild in an editor. Fix MODULE_VERSION, check if MODULE_AUTHOR is still the same
 * In the CPAN tab, open META.json or META.yml
 * Compare the contents there with the specified dependencies. Add whatever is missing (always convert the version numbers). corelist and CPAN search help.
 * Add SRC_TEST="do parallel" if not yet there.
