rem  build.bat - command-line build for the Loop project (PIC16F13145 / XC8)
rem
rem  Usage:
rem     build.bat            configure (if needed) and build
rem     build.bat rebuild    clean, then configure and build
rem     build.bat clean      remove the build tree and output artifacts
rem
rem  Requires CMake and Ninja on PATH. The XC8 compiler is referenced with an
rem  absolute path by the generated toolchain file, so it need not be on PATH.
