+README_os_390.txt for version 7.0aa of Vim: Vi IMproved.
+
+Welcome to the OS/390 Unix port of VIM.
+
+ATTENTION: THIS IS AN _ALPHA_ VERSION!!!
+I expect you to know how to handle alpha software!
+
+This port was done by Ralf Schandl <schandl@de.ibm.com>.
+This port is not maintained or supported by IBM!!
+
+
+For the list of changes see runtime/doc/os_390.txt.
+
+
+Compiling:
+----------
+
+Note: After the file configure was created via autoconf, it had been
+      handedited, to make the test for ICEConnectionNumber work.
+      DO NOT run autoconf again!
+
+Without X11:
+
+If you build VIM without X11 support, compiling and building is nearly
+straightforward. The only restriction is, that you can't call make from the
+VIM toplevel directory. Change to the src directory first and call make from
+there. Here is a what to do:
+
+    # Don't use c89!
+    # Make additional symbols visible.
+    # Allow intermixing of compiler options and files.
+
+    $ export CC=cc
+    $ export CFLAGS=-D_ALL_SOURCE
+    $ export _CC_CCMODE=1
+    $./configure --enable-max-features --without-x --enable-gui=no
+    $ cd src
+    $ make
+    $ make test
+
+      Note: Test 28 will be reported as failed. This is because diff can't
+	    compare files containing '\0' characters. Test 11 will fail if you
+	    don't have gzip.
+
+    $ make install
+
+
+With X11:
+
+There are two ways for building VIM with X11 support. The first way is simple
+and results in a big executable (~13 Mb), the second needs a few additional
+steps and results in a much smaller executable (~4.5 Mb). This examples assume
+you want Motif.
+
+  The easy way:
+    $ export CC=cc
+    $ export CFLAGS="-D_ALL_SOURCE -W c,dll"
+    $ export LDFLAGS="-W l,dll"
+    $ export _CC_CCMODE=1
+    $ ./configure --enable-max-features --enable-gui=motif
+    $ cd src
+    $ make
+
+    With this VIM is linked statically with the X11 libraries.
+
+  The smarter way:
+    Make VIM as described above. Then create a file named 'link.sed' with the
+    following contense:
+
+	s/-lXext  *//g
+	s/-lXmu  *//g
+	s/-lXm	*/\/usr\/lib\/Xm.x /g
+	s/-lX11  */\/usr\/lib\/X11.x /g
+	s/-lXt	*//g
+	s/-lSM	*/\/usr\/lib\/SM.x /g
+	s/-lICE  */\/usr\/lib\/ICE.x /g
+
+    Then do:
+    $ rm vim
+    $ make
+
+    Now Vim is linked with the X11-DLLs.
+
+    See the Makefile and the file link.sh on how link.sed is used.
+
+
+Hint:
+-----
+Use the online help! (See weaknesses below.)
+
+Example:
+Enter ':help syntax' and then press <TAB> several times, you will switch
+through all help items containing 'syntax'. Press <ENTER> on the one you are
+interested at. Or press <Ctrl-D> and you will get a list of all items printed
+that contain 'syntax'.
+
+The helpfiles contains cross-references. Links are between '|'. Position the
+cursor on them and press <Ctrl-]> to follow this link. Use <Ctrl-T> to jump
+back.
+
+Known weaknesses:
+-----------------
+
+- You can't call make from the toplevel directory, you have to do a 'cd src'
+  first.  If you do it, make will call configure again. I don't know why and
+  didn't investigate it, there were more important things to do. If you can
+  make it work drop me a note.
+
+- The documentation was not updated for this alpha release. It contains lot of
+  ASCII dependencies, especially in examples.
+
+- Digraphs are dependent on code page 1047. Digraphs are used to enter
+  characters that normally cannot be entered by an ordinary keyboard.
+  See ":help digraphs".
+
+- Using 'ga' to show the code of the character under the cursor shows the
+  correct dec/hex/oct values, but the other informations might be missing or
+  wrong.
+
+- The sed syntax file doesn't work, it is ASCII dependent.
+
+Bugs:
+-----
+If you find a bug please inform me (schandl@de.ibm.com), don't disturb Bram
+Moolenaar. It's most likely a bug I introduced during porting or some ASCII
+dependency I didn't notice.
