This function lists the fields in one or more pre-existing cart(s).

The user can also filter the records by group name, cart type, and/or a

|
user provided search string.
|
|
Unlike <command>RD_ListCarts</command><manvolnum>7</manvolnum>,
|
|
<command>RD_ListCartsCuts</command><manvolnum>7</manvolnum> will

also fetch the full list of cuts associated with each cart.
