-//   Important note about DLL memory management when your DLL uses the

-//
-//   If your DLL exports any functions that pass String objects (or structs/
-//   classes containing nested Strings) as parameter or function results,
-//   you will need to add the library MEMMGR.LIB to both the DLL project and
-//   any other projects that use the DLL.  You will also need to use MEMMGR.LIB
-//   if any other projects which use the DLL will be performing new or delete
-//   operations on any non-TObject-derived classes which are exported from the
-//   DLL. Adding MEMMGR.LIB to your project will change the DLL and its calling
-//   EXE's to use the BORLNDMM.DLL as their memory manager.  In these cases,
-//   the file BORLNDMM.DLL should be deployed along with your DLL.
-//
-//   To avoid using BORLNDMM.DLL, pass string information using "char *" or
-//   ShortString parameters.
-//
-//   If your DLL uses the dynamic version of the RTL, you do not need to
-//   explicitly add MEMMGR.LIB as this will be done implicitly for you

-Project files to build libpng using Borland C++ Builder v5.0
-
-To use this dll, you will need to:
-
-1) add the following conditional defines to your project
-
-PNG_USE_DLL
-Z_PREFIX
-
-2) add the paths to png.h and zlib.h to your include path
-
-3) add libpng.lib or libpngstat.lib to the project.
-
-If you are using libpng.dll, libpng.dll and zlib.dll will be required for the code to run.
-
-Alternatively, the libpng.dll can be built using zlibstat.lib to produce one dll containing both the zlib and png code.
-
-See the libpng documentation for instructions on how to use the code.

-//   Important note about DLL memory management when your DLL uses the
-//   static version of the RunTime Library:
-//
-//   If your DLL exports any functions that pass String objects (or structs/
-//   classes containing nested Strings) as parameter or function results,
-//   you will need to add the library MEMMGR.LIB to both the DLL project and
-//   any other projects that use the DLL.  You will also need to use MEMMGR.LIB
-//   if any other projects which use the DLL will be performing new or delete
-//   operations on any non-TObject-derived classes which are exported from the
-//   DLL. Adding MEMMGR.LIB to your project will change the DLL and its calling
-//   EXE's to use the BORLNDMM.DLL as their memory manager.  In these cases,
-//   the file BORLNDMM.DLL should be deployed along with your DLL.
-//
-//   To avoid using BORLNDMM.DLL, pass string information using "char *" or
-//   ShortString parameters.
-//
-//   If your DLL uses the dynamic version of the RTL, you do not need to
-//   explicitly add MEMMGR.LIB as this will be done implicitly for you
