"""
Bitbar plugin for Meta Package Manager (a.k.a. the :command:`mpm` CLI).

Default update cycle is set to 7 hours so we have a chance to get user's
attention once a day. Higher frequency might ruin the system as all checks are
quite resource intensive, and Homebrew might hit GitHub's API calls quota.
