.SH DESCRIPTION
.I cyntax
is a C compiler front end.
.I Cem
(cemantics) is a link editor for
.IR cyntax .
Together they obsolete
.IR lint (1).
.PP
.I cyntax
assumes that files whose names end with `.c' are
C source programs; they are compiled to an
object file 
whose name is that of the source with `.O' substituted
for `.c'.
If all goes well
it will invoke the link editor
on the resulting object files plus any arguments
whose names end with `.O'.
Object files contain type information \- no code.
.PP
Options
.BR \-D ,
.BR \-I ,
.BR \-U ,
.BR \-o ,
.BR \-l

.IR cc (1).
Options

are ignored.
Other options are:
.TP

.PD
.PP
.I Cem
is normally invoked only by
.IR cyntax .
It also has options, some of which
.I cyntax
can't be coerced into providing.
Besides
.B \-o
and
.B \-l
already mentioned, they are:
.TP
.B \-m
Don't believe file modification times.
These are normally used to avert redundant type checking.

.TP
.B \-v
