+@subsection Perl Modules
+
+Perl programs standing for themselves are named as any other package,
+using the lowercase upstream name.
+For Perl packages containing a single class, we use the lowercase class name,
+replace all occurrences of @code{::} by dashes and prepend the prefix
+@code{perl-}.
+So the class @code{XML::Parser} becomes @code{perl-xml-parser}.
+Modules containing several classes keep their lowercase upstream name and
+are also prepended by @code{perl-}.  Such modules tend to have the word
+@code{perl} somewhere in their name, which gets dropped in favor of the
+prefix.  For instance, @code{libwww-perl} becomes @code{perl-libwww}.
