+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.
