libjpeg-mmx has long been removed from Debian, but I will try to provide some fresh arguments.

1. Real "upstream" is the same for libjpeg62 and libjpeg-mmx. Both are derived from 6b release by the Independent JPEG Group.

2. The first point means that most security fixes for libjpeg62 can be cherry-picked for libjpeg-mmx.

3. It looks like a variant of libjpeg-mmx from [A] provides up to double performance boost for ZoneMinder GPL'd video surveilance suite. Details here [B].

What is necessary to revive the package, if at all possible?
