[R6RS] Library contents (exports)

[Anton van Straaten]

I've checked a couple of files into svn under draft/corelib: 
library-contents.html and library-contents.scm.  The latter is just 
Scheme data.  These files simply list all the exports from (most of) the 
libraries identified so far.

It's still under development - I'll commit a more complete version by 
the weekend, along with the Scheme code which generates it (the code may 
also be useful in some other contexts).  Some specific issues currently are:

* Arithmetic, I/O, Unicode and the new list library is not yet addressed.
* Factoring is not completely correct, e.g. the core probably contains 
some things it shouldn't.
* Keywords such as 'else' from cond & case are listed in some cases, and 
omitted in others.  Also, nothing distinguishes such keywords from other 
kinds of export.
