Crank 0.2.1

Crank is a project to provide a GUI toolkit to facilitate the breaking of cryptosystems. Initial focus is on the cryptanalysis of monoalphabetic substitution ciphers
These are some generic installation instructions.
The `configure shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile in each directory of the package. It may also create one or more `.h files containing system-dependent definitions. Finally, it creates a shell script `config.status that you can run in the future to recreate the current configuration, a file `config.cache that saves the results of its tests to speed up reconfiguring, and a file `config.log containing compiler output (useful mainly for debugging `configure).
If you need to do unusual things to compile the package, please try to figure out how `configure could check whether to do them, and mail diffs or instructions to the address given in the `README so they can be considered for the next release. If at some point `config.cache contains results you dont want to keep, you may remove or edit it.
The file `configure.in is used to create `configure by a program called `autoconf. You only need `configure.in if you want to change it or regenerate `configure using a newer version of `autoconf.
Enhancements:
- Added heuristic log window
- heuristic_hillclimbing produces log messages
- Main window is ghosted out better during heuristic
- Icons placed in notebook headers
- The componant GUI no longer redraws everything after a rebuild_componant_gui() call
- heuristic componants now pass out the fitness to improvement_found(), rather than let it be recalculated
- converted all "floats" to "doubles"
- added heuristic_simulated_annealing
- default field added to gui_generic
- guile interface introduced via SWIG
- dump_/instantiate_ parameters rewrote to produce scheme code
- Introduced patches to group together settings
