 .SH OPTIONS
 .TP
+\fB\-c\fP \fIpalette\fP
+By default the program uses the Doom palette for the color table lookup.
+With this option another palette can be used, \fIpalette\fP can be \fBdoom\fP,
+\fBheretic\fP, \fBhexen\fP or \fBstrife\fP.
+.TP
 .B \-p
 Preserve case. Prevent the name of the graphic files to be forced to
 lower case. For example, a sprite named \fBFRED\fP would be saved as
 .B ./sprites/FRED.ppm
 .TP
-\fB\-c\fP \fIpalette\fP
-By default the program uses the Doom palette for the color table lookup.
-With this option another palette can be used, \fIpalette\fP can be \fBdoom\fP,
-\fBheretic\fP, \fBhexen\fP or \fBstrife\fP.
+\fB\-w\fP \fIexpr\fP
+Extract only the sprites whose names match the wildcard expression \fIexpr\fP.
+By default, all sprites are extracted.
+The matching is done by calling \fBfnmatch\fP(3) with the \fIflags\fP argument
+set to 0.
+The strings are uppercased before they're passed to fnmatch() so that the
+matching is case-insensitive.
+All usual shell wildcards apply:
+
+.ta 2 12
+.nf
+	\fB*\fP matches zero or more characters
+	\fB?\fP matches one character
+	\fB[\fIrange\fB]\fR     matches one character in \fIrange\fP
+	\fB[!\fIrange\fB]\fR    matches one character not in \fIrange\fP
+	\fB\\*\fP       matches \fB*\fP
+	\fB\\?\fP       matches \fB?\fP
+	\fB\\[\fP       matches \fB[\fP
+	\fB\\\\\fP      matches \fB\\\fP
+	\fIother\fP     matches itself
+.fi
+
+See \fBfnmatch\fP(3) for more details.
