91This version of the
92.Nm
93utility was written by
94.An Thomas Klausner Aq Mt wiz@NetBSD.org .
95.Sh BUGS
96.Xr zgrep 1
97does not handle flags that take arguments if there is no whitespace
98between the flag and the argument, for example:
99.Pp
100.Dl "zgrep -enfs /etc/rpc"
101.Pp
102When more than one
103.Fl e
104flag is used matching
105should occur for any of the patterns (similar to multiple patterns
106supplied in a file with the
107.Fl f
108flag).
109.Xr zgrep 1
110only matches the last
111.Fl e
112pattern.
