The documentation is generated on-the-fly using several scripts and
programs.

Required programs:
------------------
latex
pydoc
links2
latex2html

Generating documentation:
-------------------------
Make pdf,html,txt and python-html documentation of PyWPS: run only the
'make' command.

Create each type of documentation separately:

make html       # will generate html documentation using latex2html script
make txt        # will generate text documentation from html version using links2 browser
make process    # will generate html documentation of Process.py using pydoc
