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