Change the description of a file

You can change the description associated with a file or directory without changing the file itself or the md5 checksum of the file.

In this example, you have already authenticated and saved your user name and key credentials in your home directory.
Run the pbl.py changedesc command like this:
pbl.py changedesc -l http://$external_host/cubit_api/1 --project=myproject -t pub -r /foo/bar/baz/Release.zip -d "This is the new description"
