 /**
-* Session handling class and associated functions
-*
-* This subpackage provides some functions that are useful around web
-* application session management.
-*
-* The class is intended to be as lightweight as possible while holding
-* all session data in the database:
-*  - Session hash is not predictable.
-*  - No clear text information is held in cookies.
-*  - Passwords are generally salted MD5 hashes, but individual users may
-*    have plain text passwords set by an administrator.
-*  - Temporary passwords are supported.
-*  - Logout is supported
-*  - "Remember me" cookies are supported, and will result in a new
-*    Session for each browser session.
+* RSCDS extensions to AWL Session handling
