Hgo is a collection of Go packages providing read-access to local Mercurial repositories. Only a subset of Mercurial's functionality is supported. It is possible to access revisions of files and to read changelogs, manifests, and tags.

Hgo supports the following repository features:

* revlogv1
* store
* fncache (no support for hash encoded names, though)
* dotencode

The Go packages have been implemented from scratch, based on information found in Mercurial's wiki.

The project should be considered unstable. The BUGS file lists known issues yet to be addressed.

cmd/hgo contains an example program that implements a few commands similar to a subset of Mercurial's hg.
