SWISH::Filters::ppt2txt - convert PowerPoint docs to text using catppt

This is a plug-in module that uses the catppt program to convert MS PowerPoint documents to text for indexing by Swish-e. catppt is part of the catdoc package and can be downloaded from:

    http://www.45.free.net/~vitus/software/catdoc/

The program catppt must be installed and in your PATH.

This filter does not specify input or output character encodings.

A minor optimization during spidering (i.e. when docs are in memory instead of on disk) would be to use open2() call to let catdoc read from stdin instead of from a file.
