New Initialization Scheme for SICS

The idea behind this scheme is, to have to edit only one list when adding a new feature. Let us look at the difference when adding a command or driver. Before using this scheme, there were many different places in psi/psi.c where modifications had to be added:

• when adding a new command
• prototype declaration of the command function or include statement
• inserting the command to the AddPsiCommands function
• if it is a startup command, inserting the command to the RemovePsiCommands function
• when adding a new driver
• prototype declaration of the driver creation function or include statement
• adding a "else if" clause to the CreatePsiXXX function
• in the case of an envitonment driver, also add an "else if" clause to the ConfigureController function.

With the new scheme, for a module one has one init function, with prototype "void (void)" placed in the source file of the module. In this function, for standalone commands, either AddIniCmd[1] or AddCmd[1] is called to insert a startup or normal command. To create a new driver, use either the MakeDriver function, if you want to use the MakeObject[2] command to create the driver, or the functions MakeInitializer/GetInitializer[2], if you want to do use an other factory command.
