Since Watcom C/C++ supports both 16-bit and 32-bit application development,
libraries are grouped under two major subdirectories.  The LIB286 directory
is used to contain libraries for 16-bit application development.  The LIB386
directory is used to contain libraries for 32-bit application development.

For 16-bit application development, the Intel x86 processor-dependent
libraries are placed under the \WATCOM\LIB286 directory.

For 32-bit application development, the Intel 386 and upward-compatible
processor-dependent libraries are placed under the \WATCOM\LIB386 directory.

Since Watcom C/C++ also supports several operating systems, including DOS,
OS/2, Windows 3.x and Windows NT, system-dependent libraries are grouped
under different directories underneath the processor-dependent directories.

For DOS applications, the system-dependent libraries are placed in
\WATCOM\LIB286\DOS (16-bit applications) and \WATCOM\LIB386\DOS (32-bit
applications).

For OS/2 applications, the system-dependent libraries are placed in
\WATCOM\LIB286\OS2 (16-bit applications) and \WATCOM\LIB386\OS2 (32-bit
applications).

For Microsoft Windows applications, the system-dependent libraries are
placed in \WATCOM\LIB286\WIN (16-bit applications) and \WATCOM\LIB386\WIN
(32-bit applications).

For Microsoft Windows NT applications, the system-dependent libraries are
placed in \WATCOM\LIB386\NT (32-bit applications).

For Novell NetWare 386 applications, the system-dependent libraries are
placed in \WATCOM\LIB386\NETWARE (32-bit applications).
