Following the discussion on issue #74, I will rework the appendix to clarify the situation.

The attached patch, taken from a [discussion on ask.sagemath.org](http://ask.sagemath.org/question/521/why-remove_face-uses-alexander-duality), speeds up `remove_face` for large simplicial complexes…

Don't you think it would be really good if there were at least one test of the form "# optional - chomp" in the Sage library?
In sage-4.8,
```
sage: search_src('chomp')
```
outputs 67 lines of code…

This patch implements conversions between simplicial and cubical complexes. It also implements the following: if you call
```
sage: SimplicialComplex(X)
```
it tests to see if X has a `_simplicial…

Add functionality to sage to create morphisms between simplicial complexes, and to associate to these morphisms the chain complex maps on the homological and cohomological chain complexes.

As motivated by a discussion on [sage-devel](http://groups.google.com/group/sage-devel/browse_frm/thread/7096309ff3af9d95), here are two minor documentation changes for simplicial complexes.

First, I cached the graph() of a simplicial complex. These get very big and tedious to compute as the complexes get bigger.
I added the method clique_complex to the graph class. This returns the la…

It would be very helpful if "sage -optional" and "sage -experimental" listed one- or two-sentence descriptions of each package. (Several of the packages I had to look up using Google. Also, it was…
