What steps will reproduce the problem? On Linux (Ubuntu 12.04 "Precise" using Mercurial v. 2.0.2):

1. hg clone https://code.google.com/p/program-ab/ destination directory: program-ab no changes found updating to branch default 0 files updated, 0 files merged, 0 files removed, 0 files unresolved

No files are checked out.

Looking at the repository browser online, it seems there is no source code in the repository. Will this happen eventually? I'm sure there are many people who would like to adapt program ab to their specific environment, which is pretty much impossible without the source code.

Source code is available now.
