+Libpng was written as a companion to the PNG specification, as a
+way to reduce the amount of time and effort it takes to support
+the PNG file format in application programs.  Most users will not
+have to modify the library significantly; advanced users may want
+to modify it more.  The library was coded for both users.  All
+attempts were made to make it as complete as possible, while
+keeping the code easy to understand.  Currently, this library
+only supports C.  Support for other languages is being considered.
