This is an expiring LRU cache, using Tie::Cache::LRU. Each entry
in this cache expires after 'EXPIRES' seconds (default 3600).
The cache is in RAM (see Tie::Cache::LRU).

This is a base class for implementing virtual base classes (what
some people call an abstract class). Kinda kooky. It allows you to
explicitly declare what methods are virtual and that must be
implemented by subclasses. This might seem silly, since your program
will halt and catch fire when an unimplemented virtual method is
hit anyway, but there's some benefits.
The error message is more informative. Instead of the usual "Can't
locate object method" error, you'll get one explaining that a virtual
method was left unimplemented.
Subclass authors can explicitly check to make sure they've implemented
all the necessary virtual methods. When used as part of a regression
test, it will shield against the virtual method requirements changing
out from under the subclass.
Finally, subclass authors can get an explicit list of everything
they're expected to implement.

Defines a set of symbolic constants with ordered numeric values ala
C enum types. What are they good for? Typical uses would be for giving
mnemonic names to indexes of arrays.
This not only reads easier, but can also be typo-checked at compile
time when run under use strict. That is, if you misspell Days_Fri
as Days_Fry, you'll generate a compile error.
Also capable of creating ordered bitmask constants, allowing the
easy creation of bitmask constants, allowing you to efficiently store
many true/false options within a single integer.

This class implements an ordered hash-like object. It's a cross
between a Perl hash and a linked list. Use it whenever you want the
speed and structure of a Perl hash, but the orderedness of a list.

Foomatic's database engine generates PPD files from the data in
Foomatic's XML database. It also contains scripts to directly generate
print queues and handle jobs.

This module provides an interface to concisely yet expressively create
classes Class::Meta. The intent is to provide a simpler, more meaningful
interface for creating Class::Meta classes while preserving the power
and flexibility of Class::Meta.
This module exports a number of functions that are useful for validating
and converting data types. It is intended for use in applications where
data types are more important than they typically are in Perl -- e.g.,
database applications.
OpenVMPS is a substitute implementation of Cisco Virtual Membership
Policy Server (on Catalyst [65]500 family of switches).
It is used on Cisco LAN switches to dynamically assign ports to VLANs
according to Ethernet Address.
Because it was developed solely on infomation obtained by observing the
network traffic between switches it is probably not complete but it is a
working subset of the protocol.
Note that it includes a patch from openvpms CVS that fixes a logging
function format string Vulnerability.
