Detailed Description

A SessionPilot is intended to make easier the use of a WorkSession. It receives commands, under alphanumeric form, then calls a library of Activators to interprete and run them.

Then, WorkSession just records data required to work : Rules for Selection, Dispatch ... ; File Data (InterfaceModel and results of Evaluations and Transfer as required). SessionPilot records and works with alphanumeric commands and their results (under a very simple form). It calls a list of Activators to perform the actions.

A Command can have several forms :

Thus, to a specific Norm or way of working, only Activators change. A specific Initialisation can be done by starting with a specific set of commands.

In addition, SessionPilot is a sub-type of Activator, to recognize some built-in commands : exit/x, help/?, control of command line, and commands xstep xset ... See method Do

At least, empty lines and comment lines (beginning by '#') are skipped (comment lines are display if read from file)
