+A key remapping daemon for Linux.

+## Impetus
 
 Linux lacks a good key remapping solution. In order to achieve satisfactory
 results a medley of tools need to be employed (e.g xcape, xmodmap) with the end
 result often being tethered to a specified environment (X11). keyd attempts to
 solve this problem by providing a flexible system wide daemon which remaps keys
 using kernel level input primitives (evdev, uinput).

 If you feel something is missing or find a bug you are welcome to file an issue
 on github. keyd has a minimalist (but sane) design philosophy which
 intentionally omits certain features (e.g execing arbitrary executables
 as root). Things which already exist in custom keyboard firmware like QMK are
 good candidates for inclusion.
