Spanish Ministry of Culture book search

This script has to be used with tellico (http://periapsis.org/tellico) as an external data source program.
It allows searching for books in Spanish Ministry of Culture's database (at http://www.mcu.es/bases/spa/isbn/ISBN.html).

Multiple ISBN/UPC searching is supported through the -m option:
./books_ministerio_de_cultura.py -m filename
where filename holds one ISBN or UPC per line.

Tellico data source setup:
- Source type: External Application
- Source name: Ministerio de Cultura (ES) (or whatever you want :)
- Collection type: Book Collection
- Result type: Tellico
- Path: /path/to/script/books_ministerio_de_cultura.py
- Arguments:
Title (checked) = -t %1
Person (checked) = -a %1
ISBN (checked) = -i %1
UPC (checked) = -i %1
Update (checked) = %{title}

Be sure to chmod +x it.
Depends: Python >= 2.4.x only
