Version 0.8.1
 - Updates to get G-Wrap to build equivalent modules for RScheme and
   Guile from the same specification file
   - now, pointer '*'s are not assumed to be necessary when converting
     Guile smob-values to native C types

Version 0.8.0
 - Support added for RScheme
 - Changes in the name of some functions
   - gwrap-scan-source-file (was gwrap-c-scan-source-file)
   - gwrap-open-module (was gwrap-c-open-file)
   - gwrap-assume-types-wrapped (was gwrap-c-assume-types-wrapped)
   - gwrap-close-module (was gwrap-c-close-file)
 - Some functions are removed:
   - gwrap-c-output-c
   - gwrap-c-output-h
   - gwrap-c-output-doc

Version 0.3.9
 - Prettier and more useful html documentation is generated from input files
 - Better C++ support

Version 0.3.8
 - Better ANISfication
 - Better C++ support

Version 0.3.7:
 - Improved configuration process
 - Integrated g-translate into g-wrap

Version 0.3.6:
 - Switched to automake/autoconf/libtool configuration

Version 0.3.5:
 - Generates an html file describing wrapped library

Version 0.3.4:
 - Option call-on-init in gwrap-c-open-file allows a function to be
   called upon intialization of the library wrapper. 

Version 0.3:
 - A capability for generating dynamically-linkable Guile modules
 - Automatic support for exporting functions with more than 10 arguments,
    without modification of libguile.
 - No longer relies on Slib (slib dependencies removed from output-file.scm,
    and g-wrap.scm)
 - Made generated *.h files more C++ friendly
 - New options for wrapping structures which are passed by value
   rather than by reference, and for generating C++ code.
 - new-function: New interface, automatically adds description to an
   assq list in variable "*gw:descriptions*", complete with a
   prototype and list of parameter and return types.
 - Renamed many functions -- the interface is pretty new overall.
  + define-constant     --> new-constant
  + c-file-include-local-header  --> gwrap-c-include-local-header
  + c-file-include-global-header --> gwrap-c-include-global-header
  + open-c-file		--> gwrap-c-open-file
  + output-c		--> gwrap-c-output-c
  + output-h		--> gwrap-c-output-h
  + make-wrapper-c-type --> gwrap-c-assume-types-wrapped (simpler interface)
 - Code for generating Guile wrapper code is now a Guile module
 - g-wrap-guile is now written to use Guile interpreter rather than SCM
 - types are now given symbolic keys rather than being returned in
   structures
   + new function formats:
    (add-type scheme-sym c-type-str fn-to-scm fn-from-scm fn-isa)
    (add-new-type scheme-sym the-type)
    (new-type scheme-sym c-name c-print-name c-die-name c-eq-name . options)
     + If options contains (c-gc-name "fname"), fname is called for
        protecting objects from GC
     + If options contains (pass-c-ptr? #f), type is passed as struct
       rather than pointer to struct
 - gwrap-c-open-file:
   Accepts options telling it to generate a C++ file and/or code for a
   dynamically linkable module
