Ah... stupid me... I import psp but don't even use it in the code :)
Copies a line too many from my web server scripts. My solution is as
follows. It allows me to give a psp file with variables and get back a
string with the page in html.

def psp2html(filename, variables={}):

    # Read the psp file in filename, run it through the parser and
    # the interpretor, and return the html code as result.
    directory, fname = os.path.split(filename)
    directory += "/"

    # invoke the parser
    pycode = _psp.parse(fname, directory).splitlines()
    pycode = [s.rstrip() for s in pycode]
    code = ""
    for s in pycode:
        code += s.replace(",0)", ")")+"\n"
        
    variables["req"] = StringIO.StringIO()
    exec code in variables
    return variables["req"].getvalue()
