QT and PyQT are standard Ubuntu packages. You need both installed to run the QT environment. However you also need a version of PyQT (and only PyQT, not QT) compiled under the Sage environment (so it would be installed inside the bin, lib and those folders inside the Sage folders) > > >> 2.

Each worksheet has an associated thread where all the work happens. Each worksheet also saves the state of the variables. When the user wants to execute any code, it is precompiled from Sage to Python code, then the Abstract Syntax Tree is manipulated so the result of the last line of code could be recovered, and then that code is basically executed via exec. > > >> > >> 4.

Just a few more questions: - Is there any way to tell Sage which is the "root" directory for searching files. That is, when an user executes "load foo.sage", how can the environment know where to find the file? - What happens if you load a file twice?
