I contain PythonScript, which is a very simple python script resource.

You forgot to assign to the variable "resource" in your script. For example:
c @ s e Zd ZdZdS )

This exception is raised when a path has already been cached.

I am a normal py file which must define a 'resource' global, which should
be an instance of (a subclass of) web.resource.Resource; it will be
renderred.

ResourceScriptDirectorya
L{ResourceScriptDirectory} is a resource which serves scripts from a
filesystem directory. File children of a L{ResourceScriptDirectory} will
be served using L{ResourceScript}. Directory children will be served using
another L{ResourceScriptDirectory}.
@ivar path: A C{str} giving the filesystem path in which children will be
looked up.
@ivar registry: A L{static.Registry} instance which will be used to decide
how to interpret scripts found as children of this resource.

I am an extremely simple dynamic resource; an embedded python script.
This will execute a file (usually of the extension '.epy') as Python code,
internal to the webserver.

Render me to a web client.
Load my file, execute it in a special namespace (with 'request' and
'__file__' global vars) and finish the request. Output to the web-page
will NOT be handled with print - standard output goes to the log - but
with request.write.
