    (description "@code{XML::Twig} is an XML transformation module.  Its
strong points: can be used to process huge documents while still being in tree
mode; not bound by DOM or SAX, so it is very perlish and offers a very
comprehensive set of methods; simple to use; DWIMs as much as possible.

What it doesn't offer: full SAX support (it can export SAX, but only reads
XML), full XPath support (unless you use @code{XML::Twig::XPath}), nor DOM
support.")
