Error running `make`

I know the project is still in flux, but just reporting my experience trying to get started on a fresh checkout.

You probably need a newer version of Irmin (and one that has the pure-OCaml SHA1 implementation). Try this pin:

opam pin add irmin 'https://github.com/talex5/irmin.git#js-sha'

Note that the storage format is still likely to change and any data you store may not be readable by later versions...

I've added a Travis test script to build the project, so if it's not working for anyone, they can compare with that.
