[l2h] File names

[Bek Oberin]

I want to have the file names in a personalized format, like
this:

<secnumber>-filename

or 

<secnumber>.<subsecnumber>-filename

depending if it's a subsection or not.  I have a hook that correctly
generates the filename, but I can't figure out how to put the
secnumbes in it.  Here's the sub:

# Build filenames
sub custom_title_hook {
   my $secname = shift;

   my $text = lc $secname;
   $text =~ s/\s//g;

   return $text;
}

Thanks for all your help, folks.  I appreciate the helpful replies I
have been getting!  This is pretty much the last thing, with luck.
