What difference does speed make on little repositories? They are fast enough anyway.

If you are worried about the speed of testing and iterating on your reposurgeon configuration, then just write the output of cvs2svn to a temporary file and use the temporary file as input to reposurgeon.

I can't believe you are still hung up on this! OK, just for you, here it is: cvs2git-3.0, in gorgeous pipey purity:

    #! /bin/sh
    blobfile=$(mktemp /tmp/myblobs-XXXXXX.out)
    dumpfile=$(mktemp /tmp/mydump-XXXXXX.out)
    cvs2git-2.0 --blobfile="$blobfile" --dumpfile="$dumpfile" "$@" 1>&2 &&
    cat "$blobfile" "$dumpfile"
    rm "$blobfile" "$dumpfile"

I don't think that cvs2git-2.0 outputs any junk to stdout, but just in case it does I've redirected stdout explicitly to stderr to avoid commingling it with the output of this script.
