+Status
+======
+
+libffi-3.0.12 was released on XXXXXXX.  Check the libffi web page for
+updates: <URL:http://sourceware.org/libffi/>.
+
+
+What is libffi?
+===============
+
+Compilers for high level languages generate code that follow certain
+conventions. These conventions are necessary, in part, for separate
+compilation to work. One such convention is the "calling
+convention". The "calling convention" is essentially a set of
+assumptions made by the compiler about where function arguments will
+be found on entry to a function. A "calling convention" also specifies
+where the return value for a function is found.
+
+Some programs may not know at the time of compilation what arguments
+are to be passed to a function. For instance, an interpreter may be
+told at run-time about the number and types of arguments used to call
+a given function. Libffi can be used in such programs to provide a
+bridge from the interpreter program to compiled code.
+
+The libffi library provides a portable, high level programming
+interface to various calling conventions. This allows a programmer to
+call any function specified by a call interface description at run
+time.  
+
+FFI stands for Foreign Function Interface.  A foreign function
+interface is the popular name for the interface that allows code
+written in one language to call code written in another language. The
+libffi library really only provides the lowest, machine dependent
+layer of a fully featured foreign function interface. A layer must
+exist above libffi that handles type conversions for values passed
+between the two languages.
+
+
+Supported Platforms
+===================
+
+Libffi has been ported to many different platforms.
+For specific configuration details and testing status, please

+
+Installing libffi
+=================
+
+First you must configure the distribution for your particular
+system. Go to the directory you wish to build libffi in and run the
+"configure" program found in the root directory of the libffi source
+distribution.
+
+You may want to tell configure where to install the libffi library and
+header files. To do that, use the --prefix configure switch.  Libffi
+will install under /usr/local by default. 
+
+If you want to enable extra run-time debugging checks use the the
+--enable-debug configure switch. This is useful when your program dies
+mysteriously while using libffi. 
+
+Another useful configure switch is --enable-purify-safety. Using this
+will add some extra code which will suppress certain warnings when you
+are using Purify with libffi. Only use this switch when using 
+Purify, as it will slow down the library.
+
+It's also possible to build libffi on Windows platforms with
+Microsoft's Visual C++ compiler.  In this case, use the msvcc.sh
+wrapper script during configuration like so:
+
+path/to/configure CC=path/to/msvcc.sh LD=link CPP=\"cl -nologo -EP\"
+
+For 64-bit Windows builds, use CC="path/to/msvcc.sh -m64".
+You may also need to specify --build appropriately. When building with MSVC
+under a MingW environment, you may need to remove the line in configure
+that sets 'fix_srcfile_path' to a 'cygpath' command. ('cygpath' is not
+present in MingW, and is not required when using MingW-style paths.)
+
+For iOS builds, the 'libffi.xcodeproj' Xcode project is available.
+
+Configure has many other options. Use "configure --help" to see them all.
+
+Once configure has finished, type "make". Note that you must be using
+GNU make.  You can ftp GNU make from prep.ai.mit.edu:/pub/gnu.
+
+To ensure that libffi is working as advertised, type "make check".
+This will require that you have DejaGNU installed.
+
+To install the library and header files, type "make install".

+Jesper Skov and Andrew Haley both did more than their fair share of
+stepping through the code and tracking down bugs.
+
+Thanks also to Tom Tromey for bug fixes, documentation and
+configuration help.
+
+Thanks to Jim Blandy, who provided some useful feedback on the libffi
+interface.
+
+Andreas Tobler has done a tremendous amount of work on the testsuite.
+
+Alex Oliva solved the executable page problem for SElinux.
+
+The list above is almost certainly incomplete and inaccurate.  I'm
+happy to make corrections or additions upon request.
+
+If you have a problem, or have found a bug, please send a note to the
+author at green@moxielogic.com, or the project mailing list at
+libffi-discuss@sourceware.org.
