  23 # This script is intended to populate the "gnulib" directory
  24 # with a subset of the gnulib code, as provided by "gnulib-tool".
  25 #
  26 # To use it, run this script, speficying the location of the
  27 # gnulib code as the only argument.   Some sanity-checking is done
  28 # before we commit to modifying things.   The gnulib code is placed
  29 # in the "gnulib" subdirectory, which is where the buid files expect
  30 # it to be.

  33 # If CDPATH is set, it will sometimes print the name of the directory
  34 # to which you have moved.  Unsetting CDPATH prevents this, as does
  35 # prefixing it with ".".
