I disagree that simply listing names increases a module's usability. Good examples of how to use the subs - now that is useful. But if it's a list of subs you want, you can use the following *NIX one-liner:

perl -MDevel::Symdump -le'eval"require $ARGV[0]";print for Devel::Symd
+ump->new($ARGV[0])->functions' HTML::Parser

UPDATE: or this (more) complete script:

use strict;
use warnings;

use Devel::Symdump;

my $class = shift || die "need module name";

eval "require $class";

my $obj = Devel::Symdump->new($class);
print $_,$/ for $obj->functions;
[download]

Don't forget that some CPAN author's follow the convention of prepending underscores to 'private' subs - you can filter those out easily with grep:

print $_,$/ for grep ! /::_/,  $obj->functions;
[download]

should do the trick.
