i3lock - 2.13-1+b1 main

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.
.
i3lock forks so you can combine it with an alias to 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.
