Forest(3pm)						User Contributed Perl Documentation					       Forest(3pm)

NAME

       Forest - A collection of n-ary tree related modules

DESCRIPTION

       Forest is intended to be a replacement for the Tree::Simple family of modules, and fixes many of the issues that have always bothered me
       about them. It is by no means a complete replacement yet, but should eventually grow to become that.

       For more information please refer to the individual module documentation, starting with Forest::Tree.

TODO

       More documentation
	   This is 0.09 so it is (still) lacking quite a bit of docs (I am being really lazy sorry).  Although I invite people to read the source,
	   it is quite simple really.

       More tests
	   The coverage is in the low 90s, but there is still a lot of behavioral stuff that could use some testing too.

SEE ALSO

       Tree::Simple
	   I wrote this module a few years ago and I had served me well, but recently I find myself getting frustrated with some of the uglier
	   bits of this module. So Forest is a re-write of this module.

       Tree
	   This is an ambitious project to replace all the Tree related modules with a single core implementation. There is some good code in
	   here, but the project seems to be very much on the back-burner at this time.

       OCaml port of Forest
	   Ask me about the OCaml port of this module, it is also sitting on my hard drive waiting for release. It actually helped quite a bit in
	   terms of helping me settle on the APIs for this module. Static typing can be very helpful sometimes.

BUGS

       All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to
       cpan-RT.
