|
|
Manipulate options in a .config file from the command line.
|
|
Usage:
|
|
config options command ...
|
|
commands:
|
|
--enable|-e option Enable option
|
|
--disable|-d option Disable option
|
|
--module|-m option Turn option into a module
|
|
--state|-s option Print state of option (n,y,m,undef)
|
|
|
|
--enable-after|-E beforeopt option
|
|
Enable option directly after other option
|
|
--disable-after|-D beforeopt option
|
|
Disable option directly after other option
|
|
--module-after|-M beforeopt option
|
|
Turn option into module directly after other option
|
|
|
|
commands can be repeated multiple times
|
|
|
|
options:
|
|
--file .config file to change (default .config)
|
|
|
|
config doesn't check the validity of the .config file. This is done at next
|
|
make time.
|
|
The options need to be already in the file before they can be changed,
|
|
but sometimes you can cheat with the --*-after options.
