Installation: put the class files in the zip into minecraft.jar and remove 
the META-INF folder. Pay attention to the net/client/minecraft/Minecraft.class
file, this needs to be replaced in the proper location!

You can stop reading now, the stuff below doesn't work properly yet.

This'll get you a world where the maximum height is 512.

Upcoming README for 0.2.0:

yMod is now controlled via a text file that should be in the root directory of 
minecraft.

If it's not there, the default values (see below) will be used, leading to a game 
that behaves like the unmodded one, except that the maximum height is 512 and a
big tower appears at the 0,0 chunk.

It can contain the following settings:
- extra.bits: the number of times the height limit is multiplied by 2. So:
    extra.bits=0 ==> height limit = 128 (but why would you use this?)
    extra.bits=1 ==> height limit = 256
    extra.bits=2 ==> height limit = 512 (works ok)
    extra.bits=3 ==> height limit = 1024 (pretty slow for me!)
    extra.bits=4 ==> height limit = 2048 (unbearably slow for me!)
- compact: if 'true', chunks get made smaller when they are saved to disk, leading 
    to reduced memory usage. I highly recommend you set this to true, the default.
- glass.ceiling: if 'true', a ceiling gets drawn indicating the maximum height of
    each chunk. More a debug thing, really, but can be fun to look at.
- always.noon: if 'true', the sun is always in the highest position, so you can
    always look at your bigger world.
- make.special.chunk: if 'true', a special tower gets generated at the 0,0 chunk
    so you don't have to build a pillar.
- cloud.limit: Controls the level of the clouds. The default sets them a bit
    above the maximum height.

The default settings are:
extra.bits=2
compact=true
glass.ceiling=false
always.noon=false
make.special.chunk=true
cloud.limit=height limit + 28
