+SVKBD: Simple Virtual Keyboard
This is a simple virtual keyboard, intended to be used in environments,
where no keyboard is available.

`make install` will then pick up the new file and install it accordingly.
+The following layouts are available:
+* **Mobile Layouts:**
+ * ``mobile-intl`` - A small international layout optimised for mobile devices. This layout consists of multiple layers which
+ can be switched on the fly, and overlays that appear on long-press of certain keys, adding input ability for
+ diacritics and other variants, as well as some emoji. The layers are:
+ * a basic qwerty layer
+ * a layer for numeric input, arrows, and punctuation
+ * a layer for function keys, media keys, and arrows
+ * a cyrillic layer (ЙЦУКЕН)
+ * a dialer/numeric layer
+ * ``mobile-plain`` - This is a plain layout with only a qwerty layer and numeric/punctuation layer. It was
+ originally made for [sxmo](https://sr.ht/~mil/Sxmo/).
+* **Traditional layouts**:
+ * ``en`` - An english layout without layers (QWERTY)
+ * ``de`` - A german layout (QWERTZ)
+ * ``ru`` - A russian layout (ЙЦУКЕН)
+ * ``sh`` - A serbo-croatian layout using latin script (QWERTZ)

+For layouts that consist of multiple layers, you can enable layers on program start through either the ``-l`` flag or
+through the ``SVKBD_LAYERS`` environment variable. They both take a comma separated list of layer names (as defined in
+your ``layout.*.h``). Use the ``↺`` button in the bottom-left to cycle through all the layers.
+Some layouts come with overlays that will show when certain keys are hold pressed for a longer time. For
+example, a long press on the ``a`` key will enable an overview showing all kinds of diacritic combinations for ``a``.
+Overlay functionality interferes with the ability to hold a key and have it outputted repeatedly. You can disable
+overlay functionality with the ``-O`` flag or by setting the environment variable ``SVKBD_ENABLEOVERLAYS=0``. There is
+also a key on the function layer of the keyboard itself to enable/disable this behaviour on the fly. Its label shows
+``≅`` when the overlay functionality is enabled and ``≇`` when not.
+This virtual keyboard does not actually modify the X keyboard layout, the ``mobile-intl``, ``mobile-plain`` and ``en`` layouts simply rely on a standard US QWERTY layout (setxkbmap us) being activated, the other layouts (``de``, ``ru``, ``sh``) require their respective XKB keymaps to be active.
+If you use another XKB layout you will get unpredictable output that does not match the labels on the virtual keycaps!
