These config options can be defined in ~/.mozbuild/machrc or topsrcdir/machrc. Aliases work similar to the identically named option in an hgrc. For example: [alias] browser-test = mochitest -f browser mochitest = mochitest -f plain MozReview-Commit-ID: CnOocEslRUI
==== mach ==== Mach (German for *do*) is a generic command dispatcher for the command line. To use mach, you install the mach core (a Python package), create an executable *driver* script (named whatever you want), and write mach commands. When the *driver* is executed, mach dispatches to the requested command handler automatically. To learn more, read the docs in ``docs/``.
