good first issueservice-badge
Description
Repology.org tracks package versions across a lot of package repositories.
It supports badges with number of repositories which package a given project (examples below for Firefox):
And per-repository badges with version (of given project package in given repository):
Would be nice to support these on shields.io.
PS. It also supports a big badge with packaging summary in all known repos, but I guess that's not exactly sields.io format.
