Golang library to create menubar apps- programs that live only in OSX's NSStatusBar
This is based on https://github.com/caseymrm/menuet with a few bug fixes.
Under active development. API still changing rapidly.
menuet requires OS X.

The catalog app is useful for trying many of the possible combinations of features.
