...could anyone explain why I keep getting this error?
$ cvs -z6 up -P -d ... cvs server: Updating dist/src/Tools/ht2html cvs [server aborted]: cannot open directory /projects/cvsroot/python/dist/src/Tools/ht2html: No such file or directory
it used to work...
It stopped working a week ago Thursday, and Guido & Barry know about it. The directory in question vanished from the server under mysterious circumstances. You can get going again by deleting the ht2html line in your local Tools/CVS/Entries file.
