+# For examples of use see loncom/interface/lonnotify.pm
+#
+# Can be used in following order: ...
+# &start_pick_box()
+# row1
+# row2
+# row3 ... etc.
+# &submit_row()
+# &end_pick_box()
+#
+# where row1, row 2 etc. are chosen from &role_select_row,&course_select_row,
+# &status_select_row and &email_default_row

+# Can also be used in following order:

+# &row_title()
+# &row_closure()
+# &row_title()
+# &row_closure() ... etc.
+# &submit_row()
+# &end_pick_box()
+#
+# In general a &submit_row() call should proceed the call to &end_pick_box(),
+# as this routine adds a button for form submission.

+# &start_pick_box() creates a bounding table with 1-pixel wide black border.

+# &role_select_row() provides a select box from which to choose 1 or more roles
+# &course_select_row provides ways of picking groups of courses
+# radio buttons: all, by category or by picking from a course picker pop-up
+# note: by category option is only displayed if a domain has implemented

+#
+# &status_select_row() provides a select box from which to choose 1 or more

+# set_form_elements
+#
+# Generates javascript to set form elements to values based on
+# corresponding values for the same form elements when the page was
+# previously submitted.
+#
+# Last submission values are read from hidden form elements in referring
+# page which have the same name, i.e., generated by &echo_form_input().
+#
+# Intended to be called by onload event.
+#
+# Inputs:
+# (a) Reference to hash of echoed form elements to be set.
+#
+# In the hash, keys are the form element names, and the values are the
+# element type (selectbox, radio, checkbox or text -for textbox, textarea or
+# hidden).
+#
+# (b) Optional reference to hash of stored elements to be set.
+#
+# If the page being displayed is a page which permits modification of
+# previously stored data, e.g., the first page in a multi-page submission,
+# then if stored is supplied, form elements will be set to the last stored
+# values. If user supplied values are also available for the same elements
+# these will replace the stored values.
+#
+# Output:
+#
+# javascript function - set_form_elements() which sets form elements,
+# expects an argument: formname - the name of the form according to
+# the DOM, e.g., document.compose
