-# Purpose
-#
-# Comments and uncomments #define lines in the given header file and optionally
-# sets their value or can get the value. This is to provide scripting control of
-# what preprocessor symbols, and therefore what build time configuration flags
-# are set in the 'config.h' file.
-#
-# Usage: config.pl [-f <file> | --file <file>] [-o | --force]
-#                   [set <symbol> <value> | unset <symbol> | get <symbol> |
-#                       full | realfull]

-# Full usage description provided below.

-
-Commands
-    set <symbol> [<value>]  - Uncomments or adds a #define for the <symbol> to
-                              the configuration file, and optionally making it
-                              of <value>.
-                              If the symbol isn't present in the file an error
-                              is returned.
-    unset <symbol>          - Comments out the #define for the given symbol if
-                              present in the configuration file.
-    get <symbol>            - Finds the #define for the given symbol, returning
-                              an exitcode of 0 if the symbol is found, and 1 if
-                              not. The value of the symbol is output if one is
-                              specified in the configuration file.
-    full                    - Uncomments all #define's in the configuration file
-                              excluding some reserved symbols, until the
-                              'Module configuration options' section
-    realfull                - Uncomments all #define's with no exclusions
-    baremetal               - Sets full configuration suitable for baremetal build.
-
-Options
-    -f | --file <filename>  - The file or file path for the configuration file
-                              to edit. When omitted, the following default is
-                              used:
-                                $config_file
-    -o | --force            - If the symbol isn't present in the configuration
-                              file when setting its value, a #define is
-                              appended to the end of the file.
