i3lock - improved screen locker
===============================
i3lock is a simple screen locker like slock. After starting it, you will
see a white screen (you can configure the color/an image). You can return
to your screen by entering your password.

Many little improvements have been made to i3lock over time:

- i3lock forks, so you can combine it with an alias to suspend to RAM
  (run "i3lock && echo mem > /sys/power/state" to get a locked screen
   after waking up your computer from suspend to RAM)

- You can specify either a background color or a PNG image which will be
  displayed while your screen is locked.

- You can specify whether i3lock should bell upon a wrong password.

- i3lock uses PAM and therefore is compatible with LDAP etc.

Requirements
------------
- pkg-config (or you can rewrite the Makefile by hand if you want to avoid it)
- libxcb
- libxcb-util
- libpam-dev
- libcairo-dev
- libxcb-xinerama
- libev
- libx11-dev
- libx11-xcb-dev
- libxkbfile-dev
- libxkbcommon >= 0.2.0

Running i3lock
-------------
Simply invoke the 'i3lock' command. To get out of it, enter your password.

Building i3lock
-------------
If you don't want to build against libcairo run "make NOLIBCAIRO=y", without
libcairo displaying images is not possible.
