+.Sh NAME
+.Nm ibcs2
+.Nd load iBCS2 runtime support for SCO and ISC binaries
+.Sh SYNOPSIS
+.Nm ibcs2
+.Sh DESCRIPTION
+The
+.Nm
+utility loads kernel runtime support for iBCS2 compliant programs.
+This runtime support is limited to emulation of the iBCS2
+system call interface, and is far from complete. COFF binaries
+and shared libraries are supported, however no shared libraries
+are provided with the FreeBSD distribution.
+.Sh FILES
+.Bl -tag -width /usr/share/examples/ibcs2/* -compact
+.It Pa /lkm/ibcs2_mod.o
+.It Pa /lkm/ibcs2_coff_mod.o
+iBCS2 loadable kernel modules.
+.Pp
+.It Pa /usr/share/examples/ibcs2/*
+Sample object files with which to test the emulator.
+.Sh "SEE ALSO"
+.Xr lkm 4 ,
+.Xr modload 8
+.Sh BUGS
+The emulation is very incomplete.
+.Pp
+Running dynamically linked binaries requires access to an existing
+SCO system from which you can grab the shared libraries.
+.Pp
+You can't really use this without reading the source code.
