Silk Tree 0.0.1 (Default branch)
Silk Tree propagates /etc/passwd and /etc/group files from a master to a list of hosts via SSH. The sending and receiving ends connect to each other as a non-root user. A read-only sudo program on the receiver's side makes the final modifications in /etc. Many checks are made to ensure reliable authorization updates. ACLs are used to enforce a simple security policy. Differences between old and new versions are shown. Two small scripts are included for exporting LDAP users and groups.Image

Forest::Tree::Builder(3pm)				User Contributed Perl Documentation				Forest::Tree::Builder(3pm)

NAME

       Forest::Tree::Builder - An abstract role for bottom up tree reader

SYNOPSIS

	   package MyBuilder;
	   use Moose;

	   with qw(Forest::Tree::Builder);

	   # implement required builder:

	   sub _build_subtrees {
	       return [
		   $self->create_new_subtree( ... ), # probably a recursive process
	       ];
	   }

	   my $builder = MyBuilder->new(
	       tree_class => ...,
	       ...
	   );

	   my $tree = $builder->tree;

DESCRIPTION

       Forest::Tree::Builder replaces Forest::Tree::Loader and Forest::Tree::Reader with a bottom up construction approach, which is also suitable
       for constructing Forest::Tree::Pure derived trees without excessive cloning.

       It provides a declarative API instead of an imperative one, where "tree" is lazily constructed on the first use, instead of being
       constructed immediately and "filled in" by the "load" method.

METHODS

       create_new_subtree
	   Implemented by Forest::Tree::Constructor

       _build_tree
	   Constructs a root node by using the top level "subtrees" list as the children.

       _build_subtrees
	   Build the subtrees.

	   Abstract method that should return an array ref of Forest::Tree::Pure derived objects.
