 1. About

 This is the CauseWay DOS Extender v5.0. The origin of the
 extender itself are the CauseWay source files supplied with Open Watcom ( v4.05 ).
 The other parts of the source are based on CauseWay v3.49 (or maybe v3.52 - the
 documentation is a bit unclear here). The extender and the debugger have been
 significantly modified.

 2. How to use the Extender
 
  a. The simplest usage is to replace the extender stub CWSTUB.EXE in Open Watcom's
     BINW directory with the one supplied by this package. Then just use the normal
     Open Watcom tools, including WLINK ( with "system causeway" ).
 
  b. Use WL32 (the native CauseWay linker) and an assembler that can produce OMF
     object modules (Masm, Tasm, JWasm, Nasm, ... ). This approach allows to generate
     both 16-bit and 32-bit binaries. See files tiny16.asm, tiny32.asm, small32.asm
     and flat.asm in directory samples.
