Good idea.

We also need to decide where to put the instructions.  Currently the top
level README is generic, the same file used for all tools that are
packaged that way.  We could leave it and create an egcs directory with
egcs/README, plus other files with the egcs manifesto and FAQ.  But I'm
not that happy with the very generic top-level README.
