+.Nm version.4th
+.Nd loader version string boot module
+.Sh DESCRIPTION
+The file that goes by the name of
+.Nm
+is a set of commands designed to draw the boot loader
+version at the bottom-right of the screen.
+The commands of
+.Nm
+by themselves are not enough for most uses.
+Please refer to the
+examples below for the most common situations, and to
+.Xr loader 7
+for additional commands.

+.Nm ,
+it must be included
+through the command:
+.Pp
+.Dl include version.4th
+.Pp
+This line is present in the default
+.Pa /boot/forth/menu.rc
+file, so it is not needed (and should not be re-issued) in a normal setup.

+.Pp
+.Bl -tag -width disable-module_module -compact -offset indent
+.It Ic print_version
+Prints the contents of the
+.Va loader_version
+environment variable right-justified at the column
+.Va loader_version_x
+and row
+.Va loader_version_y .
+.El
+.Pp
+The environment variables that effect its behavior are:
+.Bl -tag -width bootfile -offset indent
+.It Va loader_version
+Set automatically by
+.Xr loader 7 ,
+but you can override it by setting in
+.Xr loader.conf 5 .
+This should be the version of boot loader used.
+.It Va loader_version_x
+Sets the desired ending column position of
+.Va loader_version .
+Default is 80.
+.It Va loader_version_y
+Sets the desired ending row position of
+.Va loader_version .
+Default is 24.
+.It Va loader_color
+If set to
+.Dq Li NO
+(case-insensitive) or
+.Dq Li 0 ,
+causes the version to be printed without color
+.Pq default is ANSI Cyan .
