-Standard Windows DLL
-====================
-
-The DLL provided in the BCB/win32dll directory is meant as the sole candidate
-for distributions, based on libmng.dll, that install the DLL into the public
-Windows system-directory. The outline herein defines the requirements to
-which such a distribution must comply. If you cannot comply with these
-requirements please install the dll in the same directory as your application
-and NOT in the Windows system-directory!!!
-
-
-1) Only the DLL already assembled in the libmng distribution may be used for
-   other distributions!
-
-2) Only stable public releases are eligible for distribution! A public release
-   is one where the y-value of the x.y.z version-code is an even number.
-   Eg. 1.0.0, 1.2.1, 2.4.7, etc.
-
-3) The installation program MUST store the DLL in the Windows system-directory!
-   Eg. C:\WinNT\System32, C:\Windows98\System
-   (Note: InstallShield users can use the <SYSDIR> variable)
-
-3) The installation program MUST flag the file as a shared library!
-
-4) The installation program MUST NOT install the DLL if a newer version
-   already exists in the Windows system-directory! The standard DLL provided
-   contains the Windows-default version-numbering system. PLEASE USE IT!!
-   DO NOT rely on the date or size of the files.
-
-5) An uninstall procedure MAY NOT remove the DLL if other applications are
-   still linked to it! Proper handling as a shared library is imperitive.
-
-6) TEST IT, TEST IT, TEST IT!!! (I just can't stress this enough)
-   If you don't have enough time, let someone else test it BEFORE you
-   distribute!
-
-
-The penalty for violating these rules is inclusion of your name in the list
-of endangered but useless species (just below the GIF entry!), and on my
-blacklist. YOU HAVE BEEN FOREWARNED!
