I have items ("leaves") that can belong to one or more groups("branchs"), and every branch can own one or more items.I need to store this kind of data in a table and print it in txt format.The items belonging to two or more branchs can be printed in a tree(or not printed in the tree).
my question is, which module should I select?There are so many tree module in cpan,i don't know which one fit me best.
