It is certainly not necessary to dump your SVN repository to get access
to these cvs2svn:cvs-rev properties. To see the value of the property
for a specific version of a file, simply type

    svn propget -r 17 cvs2svn:cvs-rev $URL/trunk/fmtcrt

Admittedly, this is the inverse of the mapping that you want, but the
best approach is probably to compute the mapping once and record it in a
file that can be referenced when needed.

It is a pity that you didn't realize this problem *before* switching
over to SVN, because there would have been several things that you could
have done to retain this information during the conversion rather than
having to fish it out afterwards. Indeed, if you ran the conversion in
verbose mode and saved its output, I think the file CVS revision numbers
are listed as each SVN revision is created.
