+slock - simple screen locker
+============================
+simple screen locker utility for X.
+
+
+Requirements
+------------
+In order to build slock you need the Xlib header files.
+
+
+Installation
+------------
+Edit config.mk to match your local setup (slock is installed into
+the /usr/local namespace by default).
+
+Afterwards enter the following command to build and install slock
+(if necessary as root):
+
+ make clean install
+
+
+Running slock
+-------------
+Simply invoke the 'slock' command. To get out of it, enter your password.

+.Sh SYNOPSIS
+.Nm
+.Op Fl v
+.Op Ar cmd Op Ar arg ...
+.Sh DESCRIPTION
+.Nm
+is a simple X screen locker. If provided,
+.Ar cmd Op Ar arg ...
+is executed after the screen has been locked.
+.Sh OPTIONS
+.Bl -tag -width Ds
+.It Fl v
+Print version information to stdout and exit.
+.El
+.Sh SECURITY CONSIDERATIONS
+To make sure a locked screen can not be bypassed by switching VTs
+or killing the X server with Ctrl+Alt+Backspace, it is recommended
+to disable both in
+.Xr xorg.conf 5
+for maximum security:
+.Bd -literal -offset left
+Section "ServerFlags"
+ Option "DontVTSwitch" "True"
+ Option "DontZap" "True"
+EndSection
+.Ed
+.Sh EXAMPLES
+$
+.Nm
+/usr/sbin/s2ram
+.Sh CUSTOMIZATION
+.Nm
+can be customized by creating a custom config.h from config.def.h and
+(re)compiling the source code. This keeps it fast, secure and simple.
