This is a shell repository so that you can simultaneously work on these sub-repositories
pyclaw-sisc - the private staging repository for the PyClaw submission to SISC
pyclaw-sisc-rr - a public repository for storing reproducibility data and methods
You should be able to use most hg commands from this repository and you can treat the two sub-repositories as subdirectories.
always use hg pull -u or you will get weird states
use -S on hg status and its ilk to automatically recurse into subdirectories
Please read this http://mercurial.selenic.com/wiki/Subrepository to understand the potential traps of this approach
