The .pm files:

  doc2txt.pm
  pdf2html.pm
  pdf2xml.pm

are example modules that predate (iirc) the SWISH::Filters class. The reason 
pdf2html works in your script is this line in the pdf2html.pm file:

   @EXPORT = qw(pdf2html);

which tells Perl to make that function available in your script's namespace with 
the 'use' function.

I'd suggest using the DirTree.pl example script instead; it calls SWISH::Filter 
for you correctly.
