Added a "README" file containing text taken from the message I sent

to -current explaining how to use this sucker.

+This is a SysVR4 emulator derived from work done as part of the NetBSD
+Project by Christos Zoulas.  It has been ported to FreeBSD by Mark Newton.
+
+To use it:
+
+1.  Add "pseudo-device streams" to your kernel config file and rebuild,
+   reboot.
+
+2.  Build and install the svr4 module in /sys/modules/svr4
+
+3.  Type "svr4" to start it up.
+
+4.  Grab compat_sol26.tar.gz or compat_svr4.tar.gz from
+    http://www.freebsd.org/~newton/freebsd-svr4 and install them in
+    /compat/svr4
+
+5.  Run "sh SVR4_MAKEDEV all" in /compat/svr4/dev
+
+6.  Mount a Solaris/x86 CD-ROM on /cdrom
+
+7.  Brand any executables you want to run
+
+8.  See if they work.
+
+It's early days yet, folks -- You'll probably have trouble getting 100%
+functionality out of most things (specifically, poll() on a socket doesn't
+look like it works at the moment, so Netscape doesn't work (among other
+things)).  Patches will be appreciated (use send-pr).
