Script for creating a list of all the RelaxErrors and RelaxWarnings in a module. -- March 02, 2007 - 07:23

Hi,

I have fixed the import issue of the RelaxError and RelaxWarning
system within the 'error_import' branch (I talked about the problem in
the post at https://mail.gna.org/public/relax-devel/2007-03/msg00000.html,
Message-id: <7f080ed10703012125m7e6dff3du21e49d888cad2c02@xxxxxxxxxxxxxx>).
To create all the import statements I have used the attached script
which parses the given module and outputs the required import
statements.  This script could be useful in the future for finding
errors and warnings either missing from the import statement or
imported but not used in the code.

Cheers,

Edward
