Undocumented: reader/writer

[Bertrand Petit <plt-s@phoe.frmug.org>]

	Browsing schemef.h releals some functions not documented in
_Inside PLT MzScheme_. The functions scheme_install_type_reader() and
scheme_install_type_writer() seems of interest as the extension I'm
writing define a new type that can be read and written. How does one
use this?

	I suppose the writer gets a pointer to the value to be
written. What should it return? A scheme string? I also suppose the
reader should return a new value of the type read, but what should one
expect in the list argument?

	Thanks for your help.
