variable            description
===============     ============================================================
-p products         space separated list of js, firefox
-b branches         space separated list of branches 1.8.0, 1.8.1, 1.9.0
-T buildtypes       space separated list of build types opt debug
-e extra            optional. extra qualifier to pick build tree and mozconfig.
-B buildcommands    optional space separated list of build commands
                    clean, checkout, build. If not specified, defaults to
                    'clean checkout build'. 
                    If you wish to skip any build steps, simply specify a value
                    not containing any of the build commands, e.g. 'none'.
-v                  optional. verbose - copies log file output to stdout.
-S                  optional. summary - output tailered for use with
                    Buildbot|Tinderbox
-R                  optional. by default the browser test will start Firefox
                    Spider and execute the tests one after another in the same
                    process. -R will start an new instance of Firefox for each
                    test. This has no effect for shell based tests.
-X exclude          optional. By default the test will exclude the 
                    tests listed in spidermonkey-n-\$branch.tests, 
                    performance-\$branch.tests. exclude is a list of either
                    individual tests, manifest files or sub-directories which 
                    will override the default exclusion list.
-I include          optional. By default the test will include the 
                    JavaScript tests appropriate for the branch. include is a
                    list of either individual tests, manifest files or 
                    sub-directories which will override the default inclusion 
                    list.
-c                  optional. By default the test will exclude tests 
                    which crash on this branch, test type, build type and 
                    operating system. -c will include tests which crash. 
                    Typically this should only be used in combination with -R. 
                    This has no effect on shell based tests which execute crash
                    tests regardless.
-t                  optional. By default the test will exclude tests 
                    which time out on this branch, test type, build type and 
                    operating system. -t will include tests which timeout.

if an argument contains more than one value, it must be quoted.
