late versioning

[Lucio Crusca]

Hello *,

I'm new to bazaar and I've just decided to start using a VCS for my code. I'm 
a bit late... I already have two "versions" of a project, say branch A and 
branch B, that sooner or later will have to merge. Version A is where I 
develop new features, while version B is the stable one where I just backport 
important fixes (by hand, e.g. copy & paste from A). I call them "versions" and 
not "branches" because, as of today, they aren't under any VCS.

Now I need to implement a new feature, somewhat bigger than a simple fix, and 
the customer can't wait until the features already partially implemented in 
branch A become finished and stable: I need to implement that feature starting 
from the code of branch B and then, sometimes in the future, merge that 
feature into A when A will be stable.

What should I do to start doing things the right way? Should I "bzr init" both 
directories? And then?

Thanks in advance
Lucio.
