        !             5: .SH SYNOPSIS
        !             6: \f3i-trfil\fP [options]
        !             7: .SH DESCRIPTION
        !             8: \fII-trfil\fP filters standard input using user-designated
        !             9: strings as keys.
        !            10: .PP
        !            11: The following options may appear more than once and in any order:
        !            12: .IP \f3+\fP\fIstring\fP 0.75i
        !            13: Consider only lines containing \fIstring\fP; otherwise all lines are considered.
        !            14: .IP \f3^\fP\fIstring\fP 
        !            15: Remove lines containing \fIstring\fP from consideration (except those containing
        !            16: a string specified by the \f3!\fR option).
        !            17: .IP \f3!\fP\fIstring\fP
        !            18: Retain lines containing \fIstring\fP.
        !            19: .IP \f3\-c\fP\fIn\fP
        !            20: Print \fIn\fP context lines before (if \fIn\fP is negative) or after (if
        !            21: \fIn\fP is positive). Nonsequential context lines are separated by a
        !            22: blank line. The default is 0.
        !            23: .SH LIMITATIONS
        !            24: Trace output from Icon programs goes to standard error output, which
        !            25: cannot be piped directly into \fIi-trfil\fR. This problem can be
        !            26: circumvented by combining output streams. In \fIsh(1)\fR, this
        !            27: can be accomplished by
        !            28: .DS
        !            29: prog 2>&1 | i-trfil ...
        !            30: .DE
        !            31: while in \fIcsh(1)\fR, it can be accomplished by
        !            32: .DS
        !            33: prog |& i-trfil ...
        !            34: .DE
        !            35: .SH BUG
        !            36: If the environment variable \f3TRACE\fR is set to a nonzero value when
        !            37: \fIi-trfil\fR is running, one line of tracing is produced from
        !            38: \fIi-trfil\fR in addition to any other tracing.
