Here you can manage your global variables and counters. Global variables can be accessed using LCSGetVar(id) or LCSSetVar(id, value), and can be used as parameters for your pages. Several variables are defined from scratch: SITE_URL, your site URL. Used to calculate links.
LCS_THUMB_WIDTH, Width of generated thumbnails
LCS_THUMB_HEIGHT, Height of generated thumbnails
SITE_TITLE, used as the default page title,
SITE_KEYWORDS and SITE_DESCRIPTION, used by search engines

The counters are a little similar to variables. They represents self-incremented integers.
You can get the next value of a counter by using LCSGetNextID(id) and update (i.e increment it)with LCSUpdateNextID(id).
