AUR side:
* Using CHAR as a datatype is absolutely silly in new code, use
VARCHAR, and why do anything shorter than 255 or 512?
* On that note, almost all CHAR usages in the current schema are silly
and should be using VARCHAR- anything on the Packages table,
PackageCategories, PackageSources, TU_VoteInfo, AccountTypes,
Username/Email/Passwd/IRCNick on Users.
* Why not just make "Name" your primary key? The ID column is never used.
* This is a slight step toward removing DummyPkg stuff from the
Packages table- I'm trying to think out how to restructure that data
to make things work and still be slightly sound from a relational and
keys point of view.

Blacklist helper side:
* I won't lie, I think this is over-engineered a tad. This can be done
in a much shorter and easier to hack shell script since all you need
is package names- just pipe bsdtar output through some magic and you
have package names. I've attached a sample starter script I use for
archweb updates. I'd probably have it call bsdtar and then who knows
* Oh my, I forgot we are still on MyISAM for the AUR. Please to god
switch to InnoDB and use transactions instead.
