+============================
+
+Vim with Lua support can be built with either MSVC or MinGW (or Cygwin).
+You can use binaries from LuaBinaries.
+    http://luabinaries.sourceforge.net/
+
+1) Download and install LuaBinaries

+
+Download lua-X.Y.Z_Win32_dllw4_lib.zip for x86 or

+
+
+10. Building with Perl support
+==============================
+
+Vim with Perl support can be built with either MSVC or MinGW (or Cygwin).
+You can use binaries from ActiveState (ActivePerl) or Strawberry Perl.
+
+    http://www.activestate.com/activeperl
+    http://strawberryperl.com/
+
+When building, you need to set the following variables:
+
+    PERL:         Where perl is installed. E.g. C:\Perl, C:\Strawberry\perl
+    DYNAMIC_PERL: Whether dynamic linking is used. Usually, set to yes.
+    PERL_VER:     Perl version. E.g. 522 for Perl 5.22.X.
+
+E.g. When using MSVC (as one line):

+        PERL=C:\Perl DYNAMIC_PERL=yes PERL_VER=522
+
+
+11. Building with Ruby support
+==============================
+
+Vim with Ruby support can be built with either MSVC or MinGW (or Cygwin).
+Ruby doesn't provide the official Windows binaries.  The most widely used
+Windows binaries might be RubyInstaller.
+
+    http://rubyinstaller.org/
+
+If you use MinGW you can easily build with RubyInstaller, but if you use MSVC
+you need some tricks described below.
+(Another binary distribution is ActiveScriptRuby:
+    http://www.artonx.org/data/asr/)
+
+When building, you need to set the following variables at least:
+
+    RUBY:          Where ruby is installed. E.g. C:\Ruby22
+    DYNAMIC_RUBY:  Whether dynamic linking is used. Usually, set to yes.
+    RUBY_VER:      Ruby version. E.g. 22 for Ruby 2.2.X.
+    RUBY_VER_LONG: Ruby API version in a long format.
+                   E.g. 2.2.0 for Ruby 2.2.X.
+
+Ruby version vs. Ruby API version:
+
+    Ruby ver. | Ruby API ver.
+    =========================
+    1.8.X     | 1.8
+    1.9.[1-3] | 1.9.1
+    2.0.0     | 2.0.0
+    2.X.Y     | 2.X.0
+
+(Ruby 1.9.0 is excluded from the table because it is an unstable version.)
+
+
+A) Using MSVC
+
+If you want to link with ruby, normally you must use the same compiler as
+which was used to build the ruby binary.  RubyInstaller is built with MinGW,
+so normally you cannot use MSVC for building Vim if you want to link with
+RubyInstaller.  If you use a different complier, there are mainly two problems:
+config.h and Ruby's DLL name. Here are the steps for working around them:
+
+  1) Download and Install RubyInstaller.
+    You can install RubyInstaller with the default options and directory.
+    E.g.:
+      C:\Ruby22 (32-bit) or C:\Ruby22-x64 (64-bit)
+
+    Ruby 2.2.X is used in this example.
+
+  2) Download Ruby 2.2.X's source code and generate config.h:
+
+      cd C:\projects
+      git clone https://github.com/ruby/ruby.git -b ruby_2_2
+      cd ruby
+      win32\configure.bat
+      nmake .config.h.time
+
+    Note that ruby_2_2 is the branch name for Ruby 2.2.X's source code.
+    There is no need to build whole Ruby, just config.h is needed.
+    If you use 32-bit MSVC10, the config.h is generated in the
+    .ext\include\i386-mswin32_100 directory.
+
+  3) Install the generated config.h.
+
+      xcopy /s .ext\include C:\Ruby22\include\ruby-2.2.0
+
+    Note that 2.2.0 is Ruby API version of Ruby 2.2.X.
+
+  4) Build Vim. Note that you need to adjust some variables (as one line):
+
+      nmake -f Make_mvc.mak
+          RUBY=C:\Ruby22 DYNAMIC_RUBY=yes RUBY_VER=22 RUBY_VER_LONG=2.2.0
+          RUBY_MSVCRT_NAME=msvcrt
+          WINVER=0x500
+
+    WINVER must be set to >=0x500, when building with Ruby 2.1 or later.
+    When using this trick, you also need to set RUBY_MSVCRT_NAME to msvcrt
+    which is used for the Ruby's DLL name.
+
+B) Using MinGW
+
+Using MinGW is easier than using MSVC when linking with RubyInstaller.
+After you install RubyInstaller, just type this (as one line):
+
+    mingw32-make -f Make_ming.mak
+        RUBY=C:/Ruby22 DYNAMIC_RUBY=yes RUBY_VER=22 RUBY_VER_LONG=2.2.0
+        WINVER=0x500
+
+WINVER must be set to >=0x500, when building with Ruby 2.1 or later.
+
+
+12. Building with Tcl support
+=============================
+
+Vim with Tcl support can be built with either MSVC or MinGW (or Cygwin).
+You can use binaries from ActiveState (ActiveTcl).
+
+    http://www.activestate.com/activetcl
+
+When building, you need to set the following variables:
+
+    TCL:          Where tcl is installed. E.g. C:\Tcl86
+    DYNAMIC_TCL:  Whether dynamic linking is used. Usually, set to yes.
+    TCL_VER:      Tcl version in a short format. E.g. 86 for Tcl 8.6.X.
+    TCL_VER_LONG: Tcl version in a long format. E.g. 8.6 for Tcl 8.6.X.
+
+E.g. When using MSVC (as one line):
+
+    nmake -f Make_mvc.mak
+        TCL=C:\Tcl86 DYNAMIC_TCL=yes TCL_VER=86 TCL_VER_LONG=8.6
+
+Or when using MinGW (as one line):
+
+    mingw32-make -f Make_mingw.mak
+        TCL=C:\Tcl86 DYNAMIC_TCL=yes TCL_VER=86 TCL_VER_LONG=8.6
