Re: [Monotone-devel] Commit a child of 2 parents

[Yury Polyanskiy]

Oh, ok. I knew I was missing something obvious. Sorry for not RTFMing
enough.

I'm not talking about a quick hack but rather a complete lossless
converter from BK to monotone. The way to do this is to either integrate
infamous SourcePuller (by A.Tridgell) inside monotone. However that
would probably invoke a lot of fuss from BK people. 

The other way is to hack SP and make it call regular monotone commands.
In this latter case, of course it'd be nice if the tool worked with
standard monotone releases, not some specially patched ones. So I'm
just looking for a way to do this.

Again thanks everyone!

Yury.
