+PDCurses for DOS
+================
+
+This directory contains PDCurses source code files specific to DOS.
+
+
+Building
+--------
+
+. Choose the appropriate makefile for your compiler:
+
+	bccdos.mak	- Borland C++ 3.0+
+	gccdos.mak	- DJGPP V2
+	mscdos.mak	- Microsoft C
+	wccdos16.mak	- Watcom 10.6+ (16-bit)
+	wccdos4g.mak	- Watcom 10.6+ (32-bit)
+
+. For 16-bit compilers, you can change the memory MODEL in the makefile.
+  (Large model is the default, and recommended.)
+
+. 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 makefile
+
+  (For Watcom, use "wmake" instead of "make"; for MSVC, "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.
+
+
+Distribution Status
+-------------------
+
+The files in this directory are released to the Public Domain.
+
+
+Acknowledgements

+  Name:                                                         clipboard
+
+  Synopsis:
+        int PDC_getclipboard(char **contents, long *length);
+        int PDC_setclipboard(const char *contents, long length);
+        int PDC_freeclipboard(char *contents);
+        int PDC_clearclipboard(void);
+
+  Description:
+        PDC_getclipboard() gets the textual contents of the system's
+        clipboard. This function returns the contents of the clipboard
+        in the contents argument. It is the responsibilitiy of the
+        caller to free the memory returned, via PDC_freeclipboard().
+        The length of the clipboard contents is returned in the length
+        argument.
+
+        PDC_setclipboard copies the supplied text into the system's
+        clipboard, emptying the clipboard prior to the copy.
+
+        PDC_clearclipboard() clears the internal clipboard.
+
+  Return Values:
+        indicator of success/failure of call.
+        PDC_CLIP_SUCCESS        the call was successful
+        PDC_CLIP_MEMORY_ERROR   unable to allocate sufficient memory for
+                                the clipboard contents
+        PDC_CLIP_EMPTY          the clipboard contains no text
+        PDC_CLIP_ACCESS_ERROR   no clipboard support

+  Name:                                                         pdcsetsc
+
+  Synopsis:
+        int PDC_set_blink(bool blinkon);
+        void PDC_set_title(const char *title);
+
+  Description:
+        PDC_set_blink() toggles whether the A_BLINK attribute sets an
+        actual blink mode (TRUE), or sets the background color to high
+        intensity (FALSE). The default is platform-dependent (FALSE in
+        most cases). It returns OK if it could set the state to match
+        the given parameter, ERR otherwise. Current platforms also
+        adjust the value of COLORS according to this function -- 16 for
+        FALSE, and 8 for TRUE.
+
+        PDC_set_title() sets the title of the window in which the curses
+        program is running. This function may not do anything on some
+        platforms. (Currently it only works in Win32 and X11.)
