+PDCurses for OS/2
+=================
+
+This directory contains PDCurses source code files specific to OS/2.
+
+
+Building
+--------
+
+. Choose the appropriate makefile for your compiler:
+
+	bccos2.mak	- Borland C++ 2.0
+	gccos2.mak	- EMX 0.9b+
+	iccos2.mak	- C Set/2
+	wccos2.mak	- Watcom 10.6+ (32-bit)
+
+. Optionally, you can build in a different directory than the platform
+  directory by setting PDCURSES_SRCDIR to point to the directory where
+  you unpacked PDCurses, and changing to your target directory:
+
+	set PDCURSES_SRCDIR=c:\pdcurses
+
+. Build it:
+
+	make -f makefilename
+
+  (For Watcom, use "wmake" instead of "make"; for MSVC or C Set/2,
+  "nmake".) You'll get the libraries (pdcurses.lib or .a, depending on
+  your compiler; and panel.lib or .a), the demos (*.exe), and a lot of
+  object files. Note that the panel library is just a copy of the main
+  library, provided for convenience; both panel and curses functions are
+  in the main library.
+
+  You can also use the optional parameter "DLL=Y" with EMX, to build the 
+  library as a DLL:
+
+	make -f gccos2.mak DLL=Y
+
+
