#!/usr/bin/perl
# This is just a small script to test and play around with a
# processing queue for actions on VNDB that do not have a
# strict time limit. i.e. resizing and optimizing cover images
# and (re)generating the relation graphs. Because I'm using
# the POE framework, it will also be possible to integrate
# Multi the IRC bot in the same process.
#
# The queue is an array of commands, and should be executed
# in chronological order. Commands are in the form of
# [cmd] [arguments]
# where [cmd] is an internal command, and [arguments] a
# whitespace seperated list of arguments.
#
# Commands can be added from the web interface using shared
# memory, or from IRC if Multi is going to integrated in here.
# Usage:
# ./multi.pl [-c] [-s] [cmd1] [cmd2] ..
# -c Do not daemonize, just execute the commands specified
# on the command line and exit.
# -s Same as -c, but also execute commands in the shared
# memory processing queue.
# -a Don't do anything, just add the commands specified on
# the command line to the shared memory processing queue.
#
# Multi - core namespace for initialisation and global variables
#
