*
* For those folks who liked the Novell NetWare Network Administration
* tools, this library is an open source version of the Standard Novell CWorthy
* interface. The current library works under DOS, Windows, and Linux.
*
* This library uses the standard DOS screen color attributes which have been
* mapped to ncurses in Linux, and the Microsoft Windows Terminal API's.
*
* The DOS build of this library uses the DOS standard 0xB8000 CGA direct
* screen read/write interface.
*
* The Linux build maps to ncurses and supports most terminal types including
* Xterm, linux, and the VT100 or greater terminal types. The interface can
* be programmed to support a wide range of terminal types at both compile and
* run time and to display the output as either simple text or special chars
* specific to the detected or specified terminal type. Unicode and other
* special chars are fully supported for Linux, Xterm, and VT100 or greater
* terminal types.
*
* To make the libraries:
*
* Set the platform build value in cworthy.h.
* Only chose one option for either DOS, Linux,
* or Windows NT set to the value of 1.
*
* #define LINUX_UTIL 1 <- select Linux build
* #define DOS_UTIL 0
* #define WINDOWS_NT_UTIL 0
*
* Linux
*
* make clean
* make install
*
* DOS
*
* Install the DJGPP Compiler and tools
* on DOS or Windows. Tested on DJGPP
* gcc-4.44 version and gcc-9.0
*
* make -f Makefile.dos clean
* make -f Makefile.dos
*
* WINDOWS
*
* Install the Windows SDK from Microsoft.
* Tested on Microsoft Windows SDK
*
* nmake -f Makefile.windows clean
