how do I start PyCrust?

[7stud]

Hi,

In "wxPython in Action" it says to issue the command:

$ pywrap filename.py

but I get the error:

-bash: pywrap: command not found.  

Do I need to install PyCrust somehow?   According to wPIA, 

----
Because PyCrust is part of the wxPython distribution, it is installed along
with wxPython, including all the source code.

 I'm using python 2.4.4 and 
wxPython 2.8 for mac os 10.4, from this download:

wxPython2.8-osx-unicode-2.8.3.0-universal10.4-py2.4.dmg

I also downloaded the docs from this download:

wxPython2.8-osx-docs-demos-2.8.3.0-universal10.4-py2.4.dmg

Thanks.
