Questions about Perl and doc

[Julien ÉLIE]

Hi,

I have three little questions which puzzle me:

* why are there in mod-active the following two consecutive lines?

    $oldact = $inn::active;         # active file location
    $oldact = $inn::active;         # active file location (same; shut up, perl -w)

I do not understand why -- perhaps an issue with antediluvian Perl versions?!?


* what are in some Perl scripts lines like these ones for?

    # lint food
    print $inn::pathrun.$inn::pathlog.$inn::pathetc.$inn::newsbin;


* why are hook-perl and hook-python only available in text format in doc/?
  wouldn't it be useful to also [or only?] have them in man format in doc/man?
  Indeed, there is no "man filter_innd" or "man filter_nnrpd" for quick reference...

  And by the way, is it OK if I add symbolinc links (like actsyncd(8) -> actsync(8))
  for nocem.ctl(5) -> perl-nocem(8) and localgroups(5) -> docheckgroups(8)?
