I have been working with perl since the days of perl 4
(in the early 1990's) and have implemented a large number of complex
perl applications: including programs to parse assembler listings
and translate to WSL and modules for processing basic block graphs
to compute control and data dependencies for program slicing.
I am the maintainer for Text::Reflow and Mail::SpamFilter on CPAN
where my username is MWARD. http://search.cpan.org/~mward/
Text::Reflow is a perl XS implementation of Knuth's optimal algorithm
for line breaking a paragraph, as used in TeX.
Mail::SpamFilter is a small module which handles processing email
messages through various different spam filters and comparing
the results.
