Data::Locations is a virtual file manager which allows you to write and read data (text and binary) to and from virtual files (think of bubbles). Moreover, this manager allows you to (recursively) define "magic" insertion points in these virtual files (bubbles inside other bubbles) which can be filled in (inflated) later (through a "straw", i.e., the object's reference), at any convenient time and in any order you like. Since this software acts purely in memory, there is no slowing down through costly file input/output (i.e., no temporary files).
File-Find-Object provides Perl programmers with an object-oriented alternative to the core File::Find module for traversing a directory structure, which has some serious interface limitations. As opposed to File::Find, File-Find-Object can be instantiated, can be interrupted in the middle, has an iterative interface, and can also return results as objects.
