After unzip ExtraBackendParsers.zip, you will get DOC.pm, Xls.pm, PPT.pm and ppt2html files. 

Copy DOC.pm, Xls.pm and PPT.pm  files in the directory where Plucene::SearchEngine::Index has installed other backend parser files. 
e.g. I had to copy those at /usr/lib/perl5/site_perl/5.8.1/Plucene/SearchEngine/Index directory on my system.


DOC.pm require wvware tool. The tool is available at  http://wvware.sourceforge.net. 

Xls.pm  require SpreadSheet::ParseExcel module, its available at CPAN site.

PPT.pm require the ppt2html script, the ppt2html script usage ppthtml tool. The ppthtml is part of xlhtml package. The xlhtml is available at http://chicago.sourceforge.net/xlhtml 

Copy the ppt2html script at the directory where you find ppthtml is installed.
