Hi Robert, please use the command line interface for now. I'll see if I can get login support finished in the next week but no promises.

Hi Erik, thanks for the reply but I struggle to find how to use the command line to create a specification.

Basically, I'm trying to get the latest version of a few packages on CIPD so that I can put the version strings in the spec. `vpython -vpython-tool help` does not seem to have what I need. And the doc I linked to in the OP doesn't seem to contain related information, either.

qyearsley@ told me it's probably the `cipd` tool.

`cipd ls` is as good as the web UI, and it doesn't seem to be able to list the versions, either.

`cipd describe` requires the version string...

So I wrote a simple script to trial and error: start with the latest version on PyPi and decrement the version number until `cipd describe` is happy...

Up till recently all our cipd packages were being built from our own sources and tagged with git_revision:<SHA1> tags, so listing of versions is basically listing of git history, and thus it wasn't implemented.
