Next you must specify fields or keys for your megatest area. These

\"TARGET_OS\" or if you are in the semiconductor business perhaps
things like \"TECHNOLOGY_NODE\", \"DESIGN_KIT\" or \"METAL_STACK\".
The all caps is a convention because the variables you choose will be
available to your tests as environment variables. You can edit these
values later but it is generally a good idea to settle on them
early.
Your runs will be stored in directories specified by your
keys. Example, if you have keys OSFAMILY/VARIANT/OSVER/RELEASE you may
get a test \"build\" in a directory like this:
linux/ubuntu/11.04/rev_1.2/build

upper case recommended. Example: COMPILER_VER/RELEASE_NAME/QUAL_LEVEL
