+.SH NAME
+uuidgen \- command\-line utility to create a new UUID value
+.SH SYNOPSIS
+.B uuidgen
+[
+.B \-r
+|
+.B \-t
+]
+.SH DESCRIPTION
+The
+.B uuidgen
+program creates (and prints)
+a new universally unique identifier (UUID) using the
+.BR libuuid (3)
+library. The new UUID can reasonably be considered unique among
+all UUIDs created on the local system,
+and among UUIDs created on other systems in the past
+and in the future.
+.PP
+There are two types of UUID's which
+.B uuidgen
+can generate: time-based UUID's and random-based UUID's. By
+default
+.B uuidgen
+will generate a random-based UUID if a high-quality random number
+generator is present. Otherwise, it will chose a time-based UUID. It
+is possible to force the generation of one of these two
+UUID types by using the
+.B \-r
+or
+.B \-t
+options.
+.SH OPTIONS
+.TP
+.B \-r
+Generate a random-based UUID. This method creates a UUID consisting mostly
+of random bits. It requires that the operating system have a high
+quality random number generator, such as
+.IR /dev/random .
+.TP
+.B \-t
+Generate a time-based UUID. This method creates a UUID based on the system
+clock plus the system's ethernet hardware address, if present.
