Yesterday I commented on how I needed to change my `GRAILS_HOME` variable to point to the grails subdirectory of the grails-1.0 distribution. I did a bit more checking and discovered something interesting.
I just download the zipped binary distribution and expanded it, and it has the original directory structure. With that, I can just set the `GRAILS_HOME` variable to `c:\grails-1.0.1` as usual and everything should be fine.
