/*
* Copyright Merlijn Wajer 2012
*
* This is the uinput-mapper configuration file.
*
* We are still working out all the details, but it basically boils down to the
* following: You write the configuration entirely in the C preprocessor by
* adding the right commands (macros) to the right sections.
*
*
* As of now, there are three sections:
*
* - GLOBAL_MAP;
* This is where you set the amount of devices to be emulated (currently
* called JOYCOUNT) and the INPUT_PATH.
*
* - CONFIGURE_JOYSTICKS:
* This is where you tell uinput-mapper what buttons your new joysticks (or
* other devices) should expose. Any button not exposed here will never be
* send.
*
* Macros that make sense to use here:
* - JOYSTICK_SET_OPT(<opt>, <bit>, <device>)
* - JOYSTICK_ADD_KEY(<key>, <bit to set>, <device>)
* - JOYSTICK_SET_LIM(<absmin|absmax>, <value>, <key>)
*
* JOYSTICK_SET_LIM is mostly used for ABS_HATs.
*
* - JOYMAP:
*
* Set the key mappings here.
*
* Macros that make sense here:
* - KEYMAP(<in_key>, <out_key>, <out_type>, <device>, <val>)
*
* ----------------------------------------------------------------------------
*
* TODO:
* - For KEYMAPs, add parameter that species the INPUT_PATH to map from
* - Add support for multiple INPUT_PATH
* - Figure out more details. There's probably a lot missing.
* - Remove EV_KEY constraint in map.c and use it as arg to KEY_MAP
