Ok. CVSTrac ... Let me guess, that provides enough data to identify the changesets within the CVs logs or some such ? Instead of dealing just with individual files ... (Much of the complexity of cvs2svn (and my spiritual descendant cvs2fossil) comes from the fact that no cvs log information can be used to identify the changesets directly, and so they go through the RCS archives and then puzzle things, i.e. file revisions, together into changesets. (sourceforge, and maybe others, actually seems to truncate the log)) > Only version information is converted at this time. Wiki > and ticket conversion is TBD. Does the sqlite CVS have branches ?

And it becomes slower the farther back you go in the history due to its reverse delta storage (head without delta, and historic revisions as delta to newer until we reach head). This is essentially quadratic in the number of revisions. > Several hours are needed to perform the transfer.
