#Change DEBUGMODE to "DEBUG" in order to compile debug.h functions in, and "NDEBUG" to not compile debugging functions
#Change DESCRIPTION to modify what is displayed within a compatible shell
#Change ARCHIVED to "YES" to mark the output as archived, and "NO" to not
#Change APPVAR to "YES" to create the file as an AppVar, otherwise "NO" for programs
