-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.)
