Well, this helps somewhat. But still, IIUC, cvsps(1) is used
only to reconstruct the ``patch sets'', and to fetch the actual
revisions, `git-cvsimport' contacts the CVS repository directly:
--cut: $ nl -ba git-cvsimport--
...
182 package CVSconn;
183 # Basic CVS dialog.
184 # We're only interested in connecting and downloading, so ...
185
... not a word about the compression...
482 package main;
483
484 my $cvs = CVSconn->new($opt_d, $cvs_tree);
...
911 print "Fetching $fn v $rev\n" if $opt_v;
912 my ($tmpname, $size) = $cvs->file($fn,$rev);
...
930 unlink($tmpname);
...
--cut: $ nl -ba git-cvsimport--
