Bug#1001655: Avoid hardcoding depends on specific lzip implementations

[Daniel Baumann <daniel.baumann@progress-linux.org>]

Package: lintian
Version: 2.114.0
Severity: wishlist

Hi,

in #967083, someone requested that the lintian depends on lzip should be 
changed into an alternative depends on 'lzip | clzip' with the 
justification, that the submitter prefered clzip as his 
lzip-implementation-of-choice (for memory footprint reasons).

I'm maintaining all lzip related packages in Debian and there's a set of 
provides by all lzip compressors/decompressors packages since the jessie 
release in place.

May I therefore ask to have the current 'lzip | clzip' depends to be 
changed into either one of these:

  if only decompression is used:
  'lzip | lzip-decompressor'

  if only compression is used:
  'lzip | lzip-compressor'

  if both copmression and decompression is used:
  'lzip | lzip-alternative'

This will smoothly allow using any of the packages of the lzip family to 
be used, most notably the one I prefer: plzip (fully parallel version)

Regards,
Daniel
