A readtable is a data structure that maps characters into syntax
types for the Lisp expression parser.
In particular, a readtable indicates for
each character with syntax <i>macro character</i> what its macro
definition is. This is a mechanism by which the user may reprogram
the parser to a limited but useful extent.
See section <A HREF="node192.html#READTABLESECTION">22.1.5</A>.
