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:
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.
