                      4: i-trfil \- Icon trace filter
                      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.
