Lib/sequencer offers Multitasking

*** OK, I'm translating that --Cyril 14:34, 4 Jan 2006 (CET)

The lib/sequencer library implements one kind of cooperative multi-tasking of the event-driver kind. Unlike "pure" cooperative multi-tasking, a task cannot stop at any time (using an hypothetic yield feature) but only in lnown and stable states. That is conform to the Eiffel principles.

The principle is:

• the class LOOP_STACK manages th emulti-tasking;
• the class JOB represents a task. The task core is the continue feature, in which the task controls the whole system;
• the class READY_DESCRIPTION allows to describe in which conditions a task can be executed.

We will successively see each of those concepts.
