+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/.
