cexcept (pronounced "see except" in English) is a package providing
a Try/Catch/Throw exception handling interface for ANSI C (C89 and
subsequent ISO standards).  It does not attempt to handle "real"
exceptions like floating-point exceptions or addressing exceptions; it
is intended as an enhanced user-friendly alternative to setjmp() and
longjmp().
