Building PLOVR on Windows

I wanted to add options to plovr, specifically the ability to output a property map to use for interacting with my server using JSON.

First I installed Mercurial which is needed to get the plovr source code.  I installed it to I:\Programs\Mercurial and added that to my path.

Next I got the plovr source code:
I:\plovr\SRC>hg clone https://plovr.googlecode.com/hg/ plovr

I saw it had a build.xml file so I downloaded apache ant and unzipped it to I:\Programs\apache-ant-1.8.2, adding I:\Programs\apache-ant-1.8.2\bin to my path also.

Building produced an error that bash wasn't found, so I downloaded MSYS (MinGW not needed) and installed it to I:\Programs\msys\1.0.

Then I just started an msys shell and did:
$ cd /i/plovr/src/plovr
$ ant


And voila - /i/plovr/SRC/plovr/build/plovr.jar (i:\plovr\SRC\plovr\build\plovr.jar) is now there!
