Adds option to config.pl to force config changes
The script config.pl fails when setting a #define symbol if the symbol isn't already in the configuration header. This adds an option '--force' to append the symbol to the end of the file if it isn't already present. Also clarified usage, and added copyright to the config.pl.

# Purpose
|

#
|
||||
# Comments and uncomments #define lines in the given header file and optionally

# sets their 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> | full | realfull]

Commands
|
||||
set <symbol> [<value] - Uncomments or adds a #define for the <symnol> 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 any #define present 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
|
||||
|
||||
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 it's value, a #define is
|
||||
appended to the end of the file.
