Spot on!

I used https://en.wikipedia.org/wiki/File:Microcavia_Australis.jpg as 
the picture in my attempts to get a Cuis page on  Wikipedia.

My experience in trying get acceptance is that the format is strict and 
Wikipedia wants a lot of references to Cuis which are not on the Cuis 
web site but, e.g. conference papers referencing Cuis.

I finally quit out of frustration and lack of time.

We may have a better outcome now.

Of particular note for Cuis (vs Squeak or Pharo):
   - Scalable Vector Graphics UI with floating point coordinates
   - Unified and abstracted support for Unicode
   - Packaged Features contain transitive, versioned requirements which 
must be satisfied to autoload the package.
   - Many fewer classes in base image (~700) than Squeak (~2700) or Pharo 
(~10,000), while full IDE including command completion, syntax 
highlighting, and all the usual browsers & other tools.

This last is because Cuis is continually refactored/re-engineered to 
remove muda https://en.wikipedia.org/wiki/Muda_(Japanese_term) features 
and code which do not carry their own weight.

'''Cuis''' is an [[open source]] dialect of the [[programming language]] [[Smalltalk]].  It shares its cross-platform [[virtual machine]] with [[Squeak]], [[Pharo]], and [[NewSpeak]].  Cuis programs produced on one platform run on all major [[Operating System]] and [[CPU]] architectures.

== Introduction ==
Cuis began as a project to reduce the size of the Squeak 3.7 development image to make the IDE more comprehensible<ref>[https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev/blob/master/Documentation/CuisHistory.md "A short history of Cuis"]</ref>. Complexity puts a limit to the level of understanding of the system a person might reach, and therefore limits the things that can be done with it. Reduction of complexity is an ideal which was enshrined in ''Design Principles Behind Smalltalk'' <ref> [http://www.cs.virginia.edu/~evans/cs655/readings/smalltalk.html "Design Principles Behind Smalltalk"] </ref>.

The invocation to reduce complexity has led to a continual pruning of code in the base development image even as more features are added.  This pervasive influence has led over time to a significant divergence from siblings [[Squeak]] and [[Pharo]], a measure of which is the number of classes in the base development image.  

The number of classes is obtained by evaluating '''Smalltalk allClasses size''' in a code workspace.
