rem A batch program to build or rebuild a particular configuration,
rem just for convenience.

rem Arguments:
rem  -c  Set the configuration (default: Release)
rem  -p  Set the platform (x64 or Win32, default: Win32)
rem  -r  Target Rebuild instead of Build
rem  -t  Set the target manually (Build, Rebuild, Clean, or CleanAll)
rem  -d  Set the configuration to Debug
rem  -e  Pull in external libraries using get_externals.bat
rem  -m  Enable parallel build (enabled by default)
rem  -M  Disable parallel build
rem  -v  Increased output messages
rem  -k  Attempt to kill any running Pythons before building (usually unnecessary)
