PyCrust - The Flakiest Python Shell
Half-baked by Patrick K. O'Brien (pobrien@orbtech.com)
======================================================
What is PyCrust?
----------------
PyCrust is is an interactive Python Shell written in Python.
PyCrust can be run standalone or integrated into other development
environments or other Python applications.
Where can I get the latest files and join the mailing lists?
------------------------------------------------------------
Latest PyCrust releases:
http://sourceforge.net/project/showfiles.php?group_id=31263
PyCrust home page:
http://pycrust.sourceforge.net/
SourceForge summary page:
http://sourceforge.net/projects/pycrust/
PyCrust Mailing lists:
http://sourceforge.net/mail/?group_id=31263
What else do I need to use PyCrust?
-----------------------------------
PyCrust requires Python 2.1 or later, and wxPython 2.3.1 or later.
PyCrust uses wxPython and the Scintilla wrapper class (wxStyledTextCtrl).
Python is available at http://www.python.org/.
wxPython is available at http://www.wxpython.org/.
What is the CVS information for this README file?
