   4 # Change from generic-build-script:  added this comment block.
   5 # Based on Cygwin generic package build script, customized for nmh.
   6 #
   7 # This script is incompatible with directory names that contain spaces, etc.
   8 # To fix that, a whole bunch of shell variables need to be wrapped with "".
