  # On some platforms, we have multiple means of specifying paths. Sometimes, we need to use either one

  # windows specific path (C:/), whereas for everything else, we can default to the drive root currently
  # in use (/cygdrive/c). This has to do with how the program is built, where it is expecting to find
  # libraries and binaries, and how it tries to find them.
