If you have the XML::Simple perl module (which can be emerged as
XML-Simple), you can do
perl -MXML::Simple -le 'print XMLin(shift)->{"longdescription"}' <file>
where <file> is the metadata.xml file.
However, it appears that this field is not widely supported. Instead,
you might use something like
lynx -dump -nolist `esearch -o %h <package>`
to dump the homepage of the package as text (of course, you still need
to be online for that)
