- %BuildToolsPath% is the path to build tools on my build machine.
- %var2% is a placeholder that will be replaced by the file name when debugging. This is the only placeholder that should not be expanded by the build system. It is for the debugger's use only.
- %revision% is the git revision number that should be expanded by the build system to the current revision being built.
- %branchname% should also expand by the build system to the current branch name that is being built.
