    longDescription = ''
      BSDBuild is a cross-platform build system. Derived from the
      traditional 4.4BSD make libraries, BSDBuild allows BSD-style
      Makefiles (without BSD make extensions), and works natively
      under most operating systems and make flavors. Since BSDBuild
      is implemented as a library (as opposed to a macro package),
      Makefiles are edited directly, as opposed to being compiled
      (however, if the build directory is separate from the source
      directory, BSDBuild will produce the required Makefiles in place).
