I tried to put every subdirectory of InnoDB codebase into a chart that would explain some of relations between subsystems and modules inside the source. This is what I got (click to enlarge):
Update: Check Vadim’s diagram for a more operational view of InnoDB
Another update: There’s a vector PDF version

I’m going to fire up the plotter.
You forgot to edit the relevant article: http://en.wikipedia.org/wiki/InnoDB !
I asked this question to several people but no one knew. Why is it that, in InnoDB, there are tons of files named
0 is separator, module has to be in file name so that error messages (and other internal structures) that have filename:number tell what module the problem is, and sometimes there’s just one module, so instead of calling the file foo0main Heikki called it foo0foo ;-)
Not that much magic, I guess.
Compiler limits from back in the day — function names had to be unique in their first 8 chars. Read Ingres source to see the impact of this, or get a job at Oracle and read their source.
