Thank you.

Thats very useful.

This is on my todo list.

Hmm, I'm not sure what database we will end up using for local package
mgmt, but I presume this is for script efficiency.

Chris: what would you think of having said MySQL DB on, and new packages get linted against the database?
That should be relatively low intensity...

I'm not sure what you mean here, can you explain further?

This is wrong. It's up to the package maintainer to choose .tar.gz or
.tar.bz2, and if the package is going to be changed the cygwin version
suffix MUST be bumped.
