I checked out the hudson-CVS-repo  (du -sh hudson-cvs = 78MB) and wanted to 
convert it to hg:

[mirko at borg Software]$ hg -v convert hudson-cvs                                                                                                                       
assuming destination hudson-cvs-hg
