Simple command line client for Atlassian's Bitbucket Server (former stash) service written in Go.
You can download one of the pre-built binaries for gobbs here.
You can build and install the official repository with Go:
go get github.com/gfleury/gobbs/cmd/gobbs
This will checkout this repository into $GOPATH/src/github.com/gfleury/gobbs/, build, and install it.
It should then be available in $GOPATH/bin/gobbs
