This library allows to manipulate sessions easily by creating “namespaces”, i.e. an entry in the `$_SESSION` global variable. It also allows to manipulate flash sessions.
Each namespace has a profile. Amongst many things, it implies we can control lifetime of each namespace individually. This library can be used in conjunction of ext/session (especially to configure session).
