# The script assumes it resides in the tools/gen_scripts directory and
# the defs files will be placed in glib/src.

# To update the g[lib|module|object]_functions.defs files:
# 1. ./glib_generate_methods.sh
#    Generates glib/src/glib_functions.defs.orig and glib/src/g[lib|module|object]_functions.defs.
#    If any hunks from the patch file fail to apply, apply them manually to the
#    glib_functions.defs file, if required.
# 2. Optional: Remove glib/src/glib_functions.defs.orig.

# To update the g[lib|module|object]_functions.defs files and the patch file:
# 1. Like step 1 when updating only the g[lib|module|object]_functions.defs files.
# 2. Apply new patches manually to the glib_functions.defs file.
# 3. ./glib_generate_methods.sh --make-patch
# 4. Like step 2 when updating only the g[lib|module|object]_functions.defs files.
