Hi

Thank you for your response. 

Yes, PRCS keeps more information than RCS. RCS is just used to store
the history of files. PRCS versions directory tree as a unit and keeps
records for file adds, renames and removes. It also tracks merges. I
whould like to preserve as much information in conversion as possible.

I read some documentation of Tailor and it looked interesting. It
seems to support file renames and so on. However I didn't find out how
it supports (or does it support) tracking merges. I will look it more.

I also started to look bzrlib and how to use it directly. I think I
should start from branch and workingtree classes... 

I am not worried about how to get all information out of the PRCS. It
has relatively simple descriptor file with each version, which is easy
to parse. So I will need to figure how to replay changes to bazaar
version by version.
