+.Nd setup procedure for 32-bit compatibility on 64-bit platform
+.Sh DESCRIPTION
+The
+.Nm
+module allows
+.Nx Ns Tn /sparc64
+to run
+.Nx Ns Tn /sparc
+executables.
+.Pp
+To use
+.Nm "" ,
+one must either have
+.Dv COMPAT_NETBSD32
+in the kernel, or load the compat_netbsd32 and exec_netbsd32 kernel
+modules.
+.Pp
+Static executables typically need no additional setup.
+Dynamic binaries require the dynamic linker, plus shared libaries.  Most of
+these files will need to be placed under
+.Pa /emul/netbsd32 .
+.Pp
+The easiest method of installing support for these is via the
+.Pa emulators/netbsd32_compat14
+and
+.Pa emulators/netbsd32_compat15
+packages, provided in the
+.Nx
+packages collection.  These install 32-bit a.out and ELF compatibility
+libraries, respectively.  The details of what is actually necessary for
+correct operation are given below.  This obviously is handled by the
+emulator packages.
+.Pp
+For a.out compatibility,
+.Pa /usr/libexec/ld.so
+from a 32-bit distribution is required to exist as
+.Pa /emul/netbsd32/usr/libexec/ld.so .
+For 32-bit ELF compatibility,
+.Pa /usr/libexec/ld.elf_so
+needs to be in
+.Pa /emul/netbsd32/usr/libexec/ld.elf_so .
+.Pp
+The shared libaries for a.out binaries do not live under the
+.Pa /emul/netbsd32
+directory, but under the
+.Pa /emul/aout
+directory, where the a.out dyanmic linker will find them.
+.Pp
+.Sh BUGS
+A list of things which fail to work in compatibility mode should
+be here.
+.Pp
+IPC is not well supported.
+.Pp
+.Xr sysctl 3
+is not well supported.
