+WIN32 port of GROFF and friends done by Blake McBride
+(blake@florida-software.com) 4/14/00.
+
+This port differs from other ports in that it uses the Microsoft
+compiler.  The changes were done such that they only have effect on
+the code when compiled with the Microsoft compiler.
+
+Note that not all preprocessors and output devices have been ported;
+missing are grohtml, grolbp, grn, refer, soelim, and groff.  Besides
+these programs, no utility program has been ported.  Of course,
+gxditview (which only runs on the X Window System, the standard Unix
+GUI) is missing also.
+
+
+The following programs were used, running on Windows NT 4.0:
+
+  Microsoft Visual C++ 6.0
+  Unix utilities under NT (gzip, tar, patch)
+
+
+Build Instructions
+------------------
+
+Unpack groff (using gzip & tar) as follows:
+
+    cd \
+    gzip -dc groff-1.16.tar.gz | tar xvf -
+
+Now apply the patch file `win32-diffs':
+
+    cd \groff-1.16
+    patch -p1 < win32-diffs
+
+Build everything by typing:
+
+    nmake -f Makefile.msc
+
+You are done.
+
+The bin directory contains some .cmd files to help show how to run
+stuff.  Since Windows 95/98 doesn't understand .cmd files, if you are
+operating under that OS you'll have to rename them to .bat files. 
+.bat files do have output redirection problems.
+
+
+The changes I made fall into two categories.
+
+1.  Makefiles.  Several makefiles were added.  All makefiles were named
+    Makefile.msc.
+
+2.  The Groff build includes several scripts which generate auxiliary
+    files used by groff (such as DESC, I, R, prologue, etc). 
+
+
+Directories needed at runtime
+-----------------------------
+
+bin
+font
+tmac
+mm  (copied, including sub-directories, from contrib/mm)
