Extension languages, like Guile, Python and Tcl, can be embedded into a
C program, @footnote{Or a C++ or Fortran or Pascal program if you want.}
and thus allow the user to @emph{extend} the C program.

The way this is done is by providing a C language library with a well
defined interface.  The interface consists of a set of public and
documented C-callable routines that offer the full interpreter
functionality, and allow the conversion of data between C and the
extension language.
