+
+With the \fB--export-layers\fR option, the layers to show is specified as a
+comma-delimited list of layer numbers. Adjacent layers can be specified as
+\fIXX-YY\fR, i.e., all layers from \fIXX\fR to \fIYY\fR will be
+included. \fIXX-\R will export all layers from \fIXX\fR until the last layer
+and \fI-XX\R will export all layers from the first to \fIXX\fR.
+
+Examples:
+
+\fB--export-layers 0-4\fR Export layers \fI0-4\fR.
+
+\fB--export-layers 1\fR Export only layer \fI1\fR.
+
+\fB--export-layers 0-2,3,5-7\fR Export layer \fI0-2\fR, \fI3\fR and \fI5-7\fR.
