.SH "DESCRIPTION"
Provides a reader macro, #i, to allow use of infix notation in lisp
programmes. This is mostly useful in heavily mathematical locations,
when lisp's default prefix notation can be more verbose and confusing.
.SH OPTIONS
If (get\ :infix\ :dont-print-copyright) is T, then the copyright banner

.SH ERRORS
All errors thrown are with ERROR; there are no subclassed conditions.
.SH ENVIRONMENT

32, not 8.
