-# This (obscure) bash script finds the smallest different path between
-# path1 and path2 given as command line argument. The given paths MUST
-# be relative paths, the script is not designed to work with absolute
-# paths.
-#
-# The script will then generate Makefile code that can be saved in a
-# file and included in build system.
-#
-# For instance:
-#   depdirs-rule.sh a/b/c/d a/b/e/f
-# Will print:
-#   FULL_DEPDIRS-a/b/c/d += a/b/e/f
-#   LOCAL_DEPDIRS-a/b/c += a/b/e
-#
-# The script returns 0 except if invalid arguments are given.
