20 # Usage: update-gnulib.sh <path-to-gnulib-repository>
21 # Update our import of gnulib in the GDB source tree.
23 # This script assumes that it is being called from the gdb/gnulib
24 # subdirectory, and will verify this before proceeding.
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.
31 # The list of gnulib modules we are importing in GDB.
