====== CoBro - First Class Flexibility in Smalltalk ======
[[cobro|CoBro]] is a framework illustrating the feasibility of a practical [[start|Concept-Centric Coding (C3)]] environment.  So it provides support for 1) **documenting** an implementation with domain concepts and 2) building **malleable software** that embraces variability.  Since CoBro has a partial metacircular implementation, it also illustrates the power of using a domain meta layer for building flexible software.

The [[cobro|CoBro]] environment is implemented in Smalltalk.  The particular Smalltalk implementation used is [[http://www.cincomsmalltalk.com|VisualWorks Smalltalk]].  A free non-commercial version of VisualWorks Smalltalk exists for all major platforms so normally you should be able to use CoBro on your particular installation.  

A {{downloads:c3-cobro_poster.pdf|poster}} in which we briefly illustrate the main points of this research track is available for download.   A brief overview and a number of code examples can be found in a recent {{downloads:2007_12_13_benevol_variability_c3.pdf|presentation}} given at [[http://www.info.fundp.ac.be/benevol|Benevol 2007]].  A detailed installation procedure is presented in the [[cobro:download|Download]] section.
