RSSInjector - A program for reading a keyword-based search engine RSS feed
Copyright (C) 2005 Volatile Graphix, Inc.
This program queries a search engine (MSN or Yahoo) for a keyword phrase
and gets the results in RSS format. You can then display the results.

This program is based on the lastRSS program by Vojtech Semecky,
and was changed/added to by Daniel Kramer in April, 2005.
CONFIGURATION
Edit the $feed variable to change the RSS feed.
Edit the $cacheDir variable to change the name of the RSS feed cache directory.
INSTALLATION
Installation is simple. First, create a directory where you want to
store your cached RSS feeds. It should be named something like "RSScache".
Chmod the directory to '777'. If you choose a different name for it, make sure
to change the value of the $cacheDir variable.
Then, upload this file.
PARAMETERS
RSSInjector may be called via HTTP with a number of parameters. All of the parameters are optional
except the keyword parameter, which must be provided so you can pull a feed customized on something.
keyword = The keyword phrase used to customize the RSS feed. It should be a string. Spaces
should be replaced with a '-', a '_' or '%20'.
limit = The maximum number of items you want to display. It should be an integer.
If set to 0, then there is no limit. Defaults to 0.
link = Whether or not you want to link to the item being displayed. It should be a
'1' or a '0'. Defaults to 0.
randomize = Whether or not you want to shuffle the items. It should be a '1' or a '0'. Defaults
to 0.
format = Whether or not you want neat output (HTML paragraphs and linebreaks). It should
be a '1' or a '0'. Defaults to 1.
cache = Whether or not you want to cache the RSS feeds. It should be a '1' or a '0'.
Defaults to 1.
cachelimit = The number of seconds to store cached RSS feeds. It should be an integer.
Defaults to 86400, which is one day.
