-# NAME
-
-wvkbd - on-screen virtual keyboard for wayland compositors using wlroots
-
-# SYNOPSIS
-
-wvkbd-mobintl [OPTIONS]...
-
-*NOTE*: Your binary may have a different suffix depending on which layout you compiled.
-
-# DESCRIPTION
-
-This project aims to deliver a minimal but practically usable implementation of
-a wlroots on-screen keyboard in legible C. This will _only_ be a keyboard, not
-a feedback buzzer, led blinker, or anything that requires more than what's
-needed to input text quickly. The end product should be a static codebase that
-can be patched to add new features.
-
-## OPTIONS
-
-*-D*
-	enable debug mode.
-
-*-o*
-	print pressed keys to standard output.
-
-*-O*
-	print intersected keys to standard output.
-
-*-l* _layers_
-	comma separated list of layers in vertical/portrait mode.
-
-*--landscape-layers* _layers_
-	comma separated list of layers used in horizontal/landscape mode.
-
-*--list-layers*
-	prints a list of all available layers.
-
-*-H* _pixels_
-	Height of the keyboard in pixels, for vertical/portrait mode.
-
-*-L* _pixels_
-	Height of the keyboard in pixels, for horizontal/landscape mode
-
-*--fn* _font_
-	set font and size (e.g. DejaVu Sans 20)
-
-*--hidden*
-	Start hidden (send SIGUSR2 to show).
-
-*--alpha* _int_
-	Set alpha value (i.e. transparency) for all colors [0-255]
-	
-*--bg* _rrggbb|aa_ 
-	Set color of background
-
-*--fg* _rrggbb|aa_       
-	Set color of keys
-
-*--fg-sp* _rrggbb|aa_       
-	Set color of special keys
-
-*--press* _rrggbb|aa_       
-	Set color of pressed keys
-
-*--press-sp* _rrggbb|aa_       
-	Set color of pressed special keys
-
-*--swipe* _rrggbb|aa_       
-	Set color of swiped keys
-
-*--swipe-sp* _rrggbb|aa_       
-	Set color of swiped special keys
-
-*--text* _rrggbb|aa_       
-	Set color text on keys
-
-*--text-sp* _rrggbb|aa_       
-	Set color text on special keys
-
-*--version*
-	Print version information
-
-*-h*, *--help*
-	Print usage help 
-
-
-# SIGNALS
-
-You can send signals to wvkbd to hide/show it (e.g. using _kill_(1) with _-s_):
-
-*SIGUSR1*
-	Hide the keyboard.
-
-*SIGUSR2*
-	Show the keyboard
-
-*SIGRTMIN*
-	Toggle visibility
-
-# COMPOSE BUTTON
-
-The default mobile international layout features a Compose button (*Cmp*)
-which, when combined with another key, opens up a layout that offers variants
-for that key. This is similar to functionality that other keyboards implemented
-using a *long press* (wvkbd has no such notion, holding a key will repeat
-it like on a physical keyboard).
-
-For example, press Cmp + a to access variants with diacritics like á,à,â,ä, etc.. 
-
-Most layouts also feature the following that are less obvious:
-
-- Press Cmp and . to access more punctuation
-- Press Cmp and - or , to access 'mathematical' symbols (+,-,=,etc)
-- Press Cmp and ' or 0 or 9 to access more brackets and quotes
-- Press Cmp and q to access emojis
-
-Last, but not least, pressing Cmp + space or Cmp + ⌨  or Cmp + Abc opens up an
-index that allows you to immediately jump to any layout by name, even layouts
-not explicitly added to your layers on startup.
