There's a mailing-list dedicated to Beancount, please post questions there, so others can share in the responses. More general discussions about command-line accounting also occur on the Ledger mailing-list so you might be interested in that group as well.
You can obtain the source code from a Mercurial repository on my server or from BitBucket:
See the Installing Beancount document for more details.
