+# Nested table routines.
+#
+# Routines to display form items in a multi-row table with 2 columns.
+# Uses nested tables to divide form elements into segments.
+# For examples of use see loncom/interface/lonnotify.pm 
+#
+# Can be used in following order: ...
+# &start_pick_box()
+# row1
+# row2
+# row3   ... etc.
+# &submit_row(0
+# &end_pickbox()
+#
+# 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:
+#
+# &start_pick_box()
+# &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.
+# &submit_row() does not require a &row_closure after it.
+#  
+# &start_pick_box() creates a bounding table with 1-pixel wide black border.
+# rows should be placed between calls to &start_pick_box() and &end_pick_box.
+#
+# &row_title() adds a title in the left column for each segment.
+# &row_closure() closes a row with a 1-pixel wide black line.
+#
+# &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 
+#                selection by year, semester, department, number etc.
+#
+# &status_select_row() provides a select box from which to choose 1 or more
+#  access types (current access, prior access, and future access)  
+#
+# &email_default_row() provides text boxes for default e-mail suffixes for
+#  different authentication types in a domain.
+#
+# &row_title() and &row_closure() are called internally by the &*_select_row
+# routines, but can also be called directly to start and end rows which have 
+# needs that are not accommodated by the *_select_row() routines.
