Corporate Software Development Wiki?

gnujoshua asks: "My company would like to expand the use of its Wiki to include source code and API documentation. It would be nice to have auto-generated, syntax highlighted, and well documented source code, integrated nicely into the Wiki. Ideally, changes to source could be made right in the Wiki, barring permissions, and furthermore, it would be nice to see if it compiles against the library as well. What recommendations does Slashdot have for Wikis and scripts that could be used effectively to this end?"
