Starting a filter program as child process. The output of the filter prog 
will be piped to the swish-e process. It was a minor change to the "Index 
the current file" - routine of swish-e. It was more work to do to build in 
the config file directives.

Yes. - I've implemented a FileFilter option, which enable you to include
filters for any filetype.
e.g. for PDF the entry in the config file:

     FileFilter  .pdf   _pdf_filter.sh


The _pdf_filter.sh - prog is very simple:

#!/bin/sh
pdftotext "$1" - 2>/dev/null

... using the xpdf utility  (pdftotext).

That's is to complicated to handle for me in practice. ;-)
The filter progs have to convert the contents of a file (pdf, word, xls)
to standard text and printing it on STDOUT.
