# 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.
