-
-Micro options:
-

-Micro uses the $XDG_CONFIG_HOME/micro as the configuration directory. As per the XDG spec,
-if $XDG_CONFIG_HOME is not set, ~/.config/micro is used as the config directory.
-
-colorscheme: loads the colorscheme stored in $(configDir)/colorschemes/'option'.micro
-       default value: 'default'
-       Note that the default colorschemes (default, solarized, and solarized-tc) are not located in configDir,
-       because they are embedded in the micro binary
