"""Zephyr Check kconfigs Definitions

help_text="""
Checkconfig script scans all '*.c', '*.h' and '*.S' looking for all kconfig
items used in the Zephyr Code and validates if they are defined in any
'*.kconfig*' file.
To run script use command:
checkconfig.py [-h|--help] [-c|--complete-log] [-k|--kconfig <kconfig>]
[-e|--exclude <dir_to_exclude>]
It will send to output:
-config name
-location where config is used
-full line where the config is being used
-location were config is being defined (there could be multiple declarations)
[-c|--complete-log] is an optional parameter.
If it is not given it will print only the kconfigs not defined
If given, it will print all the kconfigs found
[-s|--subdir <subdir>] is an optional parameter.
When a directory is given it will start scan from that specific directorywith .
By default it scans from zephyr base tree
[-e|--exclude <subdir_to_exclude>] is an optional parameter.
When a subdirectory is given it will be appended to defaut exclude dirs list.
Default exclude dirs are: "doc", "sanity-out" and "outdir"
