# help_updateMenu.sh -- This function updates menu lines inside
4c79b5
# texinfo chapters.  If this function is called with the
4c79b5
# 'remove-entry' string as first argument, then the menu line related
4c79b5
# to the entry being processed is removed. If this function is called
4c79b5
# with the 'update-entry' string as first argument, then the menu line
4c79b5
# related to the entry being processed is added to the menu. If no
4c79b5
# argument is passed to this function, the 'update-entry' action is
4c79b5
# assumed.
