Before reading on, you should know some definitions used in this documentation:

• element aka tag: an instruction used to tell the package manager what to do. ie <install></install>
• attribute aka property: an additional value used to describe an element
• inline: code or text that is written in this file instead of coming from an outside source
• file: the name or location of a file to be used instead of "inline"
• location aka path: the location on the computer of a directory and/or file

There are also variables that may be used in place of a path.

• $sourcedir: The directory where the source files are contained (ie Post.php, Admin.php, etc)
• $boarddir: The directory where index.php is found. Usually one level beneath the source files are contained.
• $avatardir: The directory where the avatars may be found
• $themedir: The directory where the directories of the themes are located
• $imagesdir: The directory of the images for each theme
• $languagedir: The location of the directories of language files
• $smileysdir: The location of the smiley directory
