+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.
