  1. About

  This package contains the source code of HX DOS extender.
  It should be unzipped in HX's runtime directory. Furthermore, the 
  HX developer support is needed to get the include files used by
  this source. Download it from 

   http://www.japheth.de/Download/hxdev.zip

  Most likely it will be necessary to slightly modify the Makefiles
  supplied. Please read the comments in SRC\Makefile and Src\Dirs
  first.
  Please note that the WSOCK32 binary won't build because some modules are
  missing due to copyright issues.


  2. Requirements

  The tools required to build the binaries, modules and libraries are listed
  in SRC/MAKEFILE. For detailed info see SRC/README.TXT.


  3. Files Overview

  þ Bin\SHRMZHDR.EXE: simple tool to shink the size of the DOS MZ header
    to the minimum.

  þ Bin\SETMZHDR.EXE: simple tool to modify the DOS MZ header for the
    HDPMI binary. This is done immediately after the link step.

  þ Src: this sub directory finally contains the HX source itself:
