requirements

Can reliably create 100% accurate release tarballs
Fast at redoing tarballs
Semi-fast at l10n and documentation retrieval
Can tag
Can support meta-constructs such as KTP (consisting of arbitrary sub-recipes)
Configuration files for projects (recipes) containing information like the svn protocol to use, the name/module/component, random settings...
(Supports injection of arbitrary code to manipulate the tarball) <- questionable need (used to be version fiddling in amarok2.rb)

feature list

Tarball creation
Automatic retrieval of l10n into the tar source tree
Automatic retrieval of documentation and its l10n into the tar source tree
Instead of operating on branches, operation on origins (trunk/stable) as per quickgit.kde.org is preferred
- l10n-branch (trunk/stable) is automatically mapped from quickgit.kde.org
ChangeLog generation from commit keywords BUG/FEATURE/... (secondary util)
Tag generation (secondary util)

Changelog generation must be detatched from tarball creation because both must be re-doable in the fastest possible manner
Tagging must be detatched from tarball creation because tarballs are easy to redo, tags not so much.
Tagging can result in a tar in which case the secondary util will simply exec the primary one once tagged
