Well, I've finally gotten around to converting the gcc repository (the
repository whose top-level directory contains the file named
"MAINTAINERS").  In case you're interested, here's the stats:

I converted using the following command line:

    $ cvs2svn.py -v --skip-cleanup --dump-only         \
        --force-tag=pchmerge-branchpoint               \
        --force-branch=egcs_ss_19980502                \
        --force-branch=gcc-3_2-rhl8-branchpoint        \
        --force-branch=x86-64-branch                   \
        gcc-cvs/gcc > outfile

I loaded it with the following command line:

    $ time svnadmin load foo-repos/ < cvs2svn-dump

And without further ado, the statistics:

----------------------------------------------------------------------
----------------------------------------------------------------------
The entire conversion was done on a Linux system with a 2.4ghz P4 with
1GB of RAM and a really really slow 80GB disk.
