May I suggest broadening the discussion: applications: * Homework / grading * Lecture/Talk * Collaboration on Text Books/ Study Guides Some functionality that these might imply: * collect worksheets in a structure (tree view) * share code/data between worksheets e.g., each sheet

It might be a good idea to implement the previously discussed idea of not downloading worksheets with all the bzipped history for this, otherwise the downloads would be truly jumbo. Unfortunately I do not have the expertise to implement the download with history versus download latest version

Hello, I'm creating a Sage wrapper for a numerics package called Clawpack. Clawpack works like so: when a user compiles their custom subroutines against a library an executable is produced as output. The executable then uses information stored in two, possibly more text files called claw.data
