rem to provide a shell prompt in the unix-like build environment on Windows.

rem To build the OpenPilot software we need few tools in the PATH.
rem Here we attempt to guess tools location using PATH or set them
rem directly using hard-coded locations, if not found in PATH.
rem You may want to update paths according to your installation.
rem
rem Also you can add any paths below just by adding extra call :which
rem lines with the following parameters:
rem  - environment variable which will be set to the path found (or empty)
rem  - expected directory which will be tried if not found in the current PATH
rem  - any executable file which is expected to be found in PATH or directory
rem All they will be added to the PATH in order of appearance.
