 Control flow is this (begin reading with ossdl_off_filter()):
 ossdl_off_additional_directories <-- ossdl_off_filter --> ossdl_off_rewriter --> ossdl_off_exclude_match
+
+As this plugin hooks into the PHP output buffer "ossdl_off_filter" cannot have any parameters (beyond the obvious one, that is.)
+Therefore these global variables are used:
+ - $ossdl_off_blog_url		String: the blog's URL ( get_option('siteurl') )
+ - $ossdl_off_cdn_url		String: URL of the CDN domain
+ - $ossdl_off_include_dirs	String: directories to include in static file matching, comma-delimited list
+ - $arr_of_excludes		Array: strings which indicate that a given element should not be rewritten (i.e., ".php")
+
+ - $ossdl_off_rootrelative	Boolean: if true, modifies root-relative links (default is false)
