+     iso-image-source
+                   Create a NetBSD installation CD-ROM image in the
+                   RELEASEDIR/iso directory.  The CD-ROM file system will have
+                   a layout as described in release(7).  It will have top
+                   level directories for the machine type and source.
+
+                   For most machine types, the CD-ROM will be bootable, and
+                   will automatically run the sysinst(8) menu-based installa-
+                   tion program, which can be used to install or upgrade a
+                   NetBSD system.  Bootable CD-ROMs also contain tools that
+                   may be useful in repairing a damaged NetBSD installation.
+
+                   Before ``make iso-image-source'' is attempted, RELEASEDIR
+                   must be populated by ``make sourcesets release'' or equiva-
+                   lent.
+
+                   Note that other, smaller, CD-ROM images may be created in
+                   the RELEASEDIR/MACHINE/installation/cdrom directory by
+                   ``make release''.  These smaller images usually contain the
+                   same tools as the larger images in RELEASEDIR/iso, but do
+                   not contain additional content such as the distribution
+                   sets.
+
+                   Note that the mac68k port still uses an older method of
+                   creating CD-ROM images.  This requires the mkisofs(1) util-
+                   ity, which is not part of NetBSD, but which can be
+                   installed from pkgsrc/sysutils/cdrtools.
