mash

Hi

I have installed java and mash but I am getting this error message on the command prompt-

Javac is not recognized as an internal or external command, operable program or batch file.

I have added to the system variable named path to C:\mash\bin;C:\Java\jdk1.7.0_10\bin

and added to the Add new environment variable MASH_ENV_PATH containing.;C:\mash\env
