Summary: manual.cls contains an invalid pdf-inquiry

Initial Comment:
I tried to compile the documentation for Python 2.4.1
(download today)
but it fails with the message:

  pdfTeX error (ext1): \pdfinfo used while \pdfoutput
is not set.

This is caused by the \pdfinfo call in manual.cls on
line 72.
I am using teTeX 3.0 where the LaTeX format is based on
pdftex. Therefore, the inquiry for pdf, done in
manual.cls with

  \@ifundefined{pdfinfo}{}{...}
  
always returns true, for both pdf and dvi output.
A better choice woud be using \ifpdf defined in python.sty

Thanks, anyway for the great program!

Seems to be also in howto.cls. Closed bug #1071094 as
duplicate of this.
