projects/README.projects

-This directory contains project files for building zlib under various
-Integrated Development Environments (IDE).
-
-If you wish to submit a new project to this directory, you should comply
-to the following requirements.  Otherwise (e.g. if you wish to integrate
-a custom piece of code that changes the zlib interface or its behavior),
-please consider submitting the project to the contrib directory.
-
-
-Requirements
-============
-
-- The project must build zlib using the source files from the official
-  zlib source distribution, exclusively.
-
-- If the project produces redistributable builds (e.g. shared objects
-  or DLL files), these builds must be compatible to those produced by
-  makefiles, if such makefiles exist in the zlib distribution.
-  In particular, if the project produces a DLL build for the Win32
-  platform, this build must comply to the officially-ammended Win32 DLL
-  Application Binary Interface (ABI), described in win32/DLL_FAQ.txt.
-
-- The project may provide additional build targets, which depend on
-  3rd-party (unofficially-supported) software, present in the contrib
-  directory.  For example, it is possible to provide an "ASM build",
-  besides the officially-supported build, and have ASM source files
-  among its dependencies.
-
-- If there are significant differences between the project files created
-  by different versions of an IDE (e.g. Visual C++ 6.0 vs. 7.0), the name
-  of the project directory should contain the version number of the IDE
-  for which the project is intended (e.g. "visualc6" for Visual C++ 6.0,
-  or "visualc7" for Visual C++ 7.0 and 7.1).
-
