USAGE

    groupType [(<group> | <group-list> ([+|-]<group-type>)*)]

DESCRIPTION

With no arguments, this lists the valid group types. Given the name of a group, it lists the types of the group. Given a group-list and a list of types, it sets the type of all groups in the list and then lists the groups' new types.

When setting the group types with this command, you are starting from scratch, just as you would be when creating the group with addGroup and you must specify all of the types (other than defaults you don't wish to override). If you just want to change some types, use changeGroupType.

Type names are normally listed with no - or + preceding them. Using a + before the name is essentially equivalent to using nothing. Using a -, on the other hand, causes the type to be removed if it would otherwise have been created by default. For example, to create a HIDDEN group with no incoming bias links, use the -BIASED type. You should think of the - as a minus, not as a dash.

EXAMPLES

    lens> groupType
