11 Manipulate options in a .config file from the command line.
13 $myname options command ...
15 --enable|-e option Enable option

26 Enable option directly after other option
27 --disable-after|-D beforeopt option
28 Disable option directly after other option
29 --module-after|-M beforeopt option
30 Turn option into module directly after other option
32 commands can be repeated multiple times
35 --file config-file .config file to change (default .config)
36 --keep-case|-k Keep next symbols' case (dont' upper-case it)
38 $myname doesn't check the validity of the .config file. This is done at next
41 By default, $myname will upper-case the given symbol. Use --keep-case to keep
42 the case of all following symbols unchanged.
44 $myname uses 'CONFIG_' as the default symbol prefix. Set the environment
45 variable CONFIG_ to the prefix to use. Eg.: CONFIG_="FOO_" $myname ...
