+NAME
+quadsections -- Create image sections
+.ih
+USAGE
+quadsplit images
+.ih
+PARAMETERS
+.ls images
+List of image names for images in \fBquadformat\fR.
+.le
+.ls window = "datasec" (datasec|trimsec|biassec)
+Type of section to output.  The choices are "datasec" for the amplifier
+section which includes the bias if any is present, "trimsec" for the trim
+section, and "biassec" for the bias section.
+.le
+.ls section = ""
+Section to be overlapped.  The output sections will be the parts of the
+amplifier windows which are included within this section.
+.le
+.ls template = ""
+Template for producing the output.  The template replaces occurs of
+$I with the image name, $S with the section, and $A with the amplifier
+label.  If none is specified then the default template "$I$S\\n" is
+used which produces the image name with section separated by new-lines.
+The special characters "\n" is the new-line and the extra "\" is
+required to pass the new-line through to the formatting routine.

+DESCRIPTION
+Images in "quadformat" (see help topic \fBquadformat\fR) are broken down
+in sections and written to the standard output in a specified format.
+.ih
