Having child-tickets is extremely useful when it comes to
managing multiple releases (ie. a single 'bug-report' ticket and

tickets. It has the following features:

It is possible to control in trac.ini the following aspects of
child-ticket creation/viewing:

allow/disallow child-tickets for a certain type of ticket
to define the table headers displayed in the parent ticket
to define a default for the child type to be created
restrict the type of child-tickets
to define which fields are inherited by child-tickets
