# Does a case-insensitive search for a regular expression in the help texts of
|
|
# symbols and choices and the prompts of menus and comments. Prints the
|
|
# matching items together with their locations and the matching text.
|
|
#
|
|
# Usage:
|
|
#
|
|
# $ make [ARCH=<arch>] scriptconfig SCRIPT=Kconfiglib/examples/help_grep.py SCRIPT_ARG=<regex>
|
|
#
|
|
# Shortened example output for SCRIPT_ARG=general:
|
|
#
|
|
# menu "General setup"
|
|
# location: init/Kconfig:39
|
|
#
|
|
# config SYSVIPC
|
|
# bool
|
|
# prompt "System V IPC"
|
|
# help
|
|
# ...
|
|
# exchange information. It is generally considered to be a good thing,
