  20 # Usage: update-gnulib.sh <path-to-gnulib-repository>
  21 # Update our import of gnulib in the GDB source tree.
  22 #
  23 # This script assumes that it is being called from the gdb/gnulib
  24 # subdirectory, and will verify this before proceeding.
  25 #
  26 # This script will also make a number of other verifications:
  27 #   . The gnulib version (it should match $GNULIB_COMMIT_SHA1).
  28 #   . The correct versions of the auto-tools that are used to
  29 #     regenerate the various scripts and Makefiles are on the PATH.
  30
  31 # The list of gnulib modules we are importing in GDB.
