Initialization & Provisioning
The Wolfram Language allows persistent storage of information about how new sessions should be initialized. The persistent storage uses the general persistent value mechanism, and can be specific to a user, a machine, an installation or more.
Default System-Wide Initialization
$Initialization — symbol to release and evaluate after main system initialization
$InitializationContexts — symbol giving a list of contexts to be loaded with Needs
$PreInitialization — symbol to release and evaluate before main system initialization
Termination
$Epilog — symbol to evaluate when a session ends
Initialization for Specific Symbols
InitializationValue — settable value to be assigned to a symbol on startup
$PersistenceBase — default persistence location (session, local, cloud, etc.)
EvaluationEnvironment — option to specify when an initialization value should be used
$NoValue — special initialization value for symbols that causes any value to be cleared
Initialize — perform initialization for individual symbols or the whole system
$PersistencePath — default places to search for initialization information
InitializationObjects — give a list of all initialization objects
