Records printer
~~~~~~~~~~~~~~~

The `(larceny records printer)` library exports the
two procedures described below.  These procedures
can be used to override Larceny's usual printing
of records and opaque types that were defined using
the records libraries.

proc:rtd-printer[args="rtd",result="maybe-procedure"]

Given a record type descriptor, returns its custom
print procedure, or returns false if the rtd has no
custom print procedure.

proc:rtd-printer-set![args="rtd printer"]

Given a record type descriptor _rtd_ and a
_printer_ for instances of that rtd, installs
_printer_ as a custom print procedure for _rtd_.
The _printer_ should be a procedure that,
given an instance of the rtd and a textual
output port, writes a representation of the
instance to the port.
