* call/cc only supports escape continuations, trying to re-invoke
a continuation will result in an error
    * during development of beta 2, I made a CPS version, but is too
slow to be useful currently, this will be addressed in IronScheme 2.0

Differences

    * all raise's are continuable in the sense they can be caught
(this is also addressed with the CPS version)

Extras

    * a generic load procedure for toplevel R6RS files
    * many extras procedures and macros in (ironscheme) library,
mostly provided by psyntax
    * syntactic CLR integration, automatic conversion of closures into
delegates

Credits

    * Abdulaziz Ghuloum and Kent Dybvig for psyntax (and friends) (and
equal?)
    * Marc Feeley for pretty-print
    * anyone else I missed

Planned to-do's (before final release)

    * testing of anything else
    * any additional CLR integration required
    * documentation

Updated (fixed/new)

    * Converted a substantial part of code still written in C# into
Scheme
    * Some minor compiler optimizations
    * Improvements with exactness of numbers
    * Added -I switch for extra library search paths
    * Added -emacs switch to let the REPL behave better as a
subprocess (as well as auto-detection of this)
    * Added extensions library for easy calling from .NET
    * Added remoting library (connects with REPL)
