+=method path
+
+ $string = $group->path;
+
+Get a string representation of a group's lineage. This is used as the substitution value for the
+C<{GROUP_PATH}> placeholder. See L<File::KDBX::Entry/Placeholders>.
+
+For a root group, the path is simply the name of the group. For deeper groups, the path is a period-separated
+sequence of group names between the root group and C<$group>, including C<$group> but I<not> the root group.
+In other words, paths of deeper groups leave the root group name out.
+
+ Database
+ -> Root # path is "Root"
+ -> Foo # path is "Foo"
+ -> Bar # path is "Foo.Bar"
+
+Yeah, it doesn't make much sense to me, either, but this matches the behavior of KeePass.
