	      Swallow Borland C Adapter v0.1a


    You do not need this unit to work wit Swallow!
    All functions are normally declared by the start-up
    code of Swallow and can be accessed by Swallow.H.

    To make sure the start-up code of Swallow is used
    you have to add at Options|Directories|Librarys...
    at _first_ the path of Swallow's c0?.obj files, e.g.
    "d:\swallow\clib;c:\tc\lib;". Then you have to enable
    the creation of a map-file by setting "Map file:segments"
    at Linker|Settings|Mapfile... Now you link your program
    again and execute the enclosed SegReg.Exe (calling
    convention: "SEGREG programname") and the program is
    ready to run. Never forget to call SegReg.Exe after
    _each_ linking!

    If you want to spread your program to someone, please
    don't forget to enclose "programname.SEG" and "SWALLOW.DRV".

    For debug purposes you can use the command line switch
    "/Real" which forces the start-up code of Swallow to
    load its Real Mode emulator for simplier debugging.

    If your debugger makes trouble with the emulator and
    you cannot simply remove Swallow's c0?.obj from your
    library because you use any Swallow function, you
    can include Swallow.C to your project and define
    "__NOSWALLOW" during compiling. Now Swallow.C emulates
    all Swallow functions and you can remove the path
    of Swallow's c0?.obj from your library path. So you
    can debug your program without Swallow.
