Retrieves repo information without relying on the git
command.
var getRepoInfo = require('git-repo-info');
var info = getRepoInfo();
info.branch //=> will be the current branch
info.sha //=> will be the current sha
info.abbreviatedSha //=> will be the first 10 chars of the current sha
info.tag //=> will be the tag for the current sha (or `null` if no tag exists)
When called without any arguments, git-repo-info
will automatically lookup upwards
into parent directories to find the first match with a .git
folder.
If passed an argument, it will be assumed to be the path to the repo's .git
folder
to inspect.
