1. Because I built it with a recent snapshot, so it requires a
snapshot or 1.5.19 (which I hope will come soon...)
2. In case building with the generic build script causes any problems,
I wanted people to have the option of keeping the 1.99.1-1 version,
but I didn't want that to be prev, since the older version is a lot
faster, and there may be some people still wanting to use it.
After a while, I'd like 1.99.1-2 to replace 1.99.1-1 as curr.
