 To register an oplist you need to register three things:
 
 * the *integration user* (user responsible for the integration of the whole program) registers all the *organizations* by mapping an integer from 1 to 50 to the short name of the organization.
-* the *organization user* (user responsible for the integration produced by an organization, typically a library or the program except its libraries) chooses the short name of the organization and registers all the *components* of this organization by mapping an integer from 1 to 50 to the short name of the component.
+* the *organization user* (user responsible for the integration produced by an organization, typically a library or the program without its libraries) chooses the short name of the organization and registers all the *components* of this organization by mapping an integer from 1 to 50 to the short name of the component.
 * the *component user* (user responsible for a component of a library or a program) registers all the *oplists* of this component by mapping an integer from 1 to 50 to the oplist.
 
 This 3 levels registration is used to enable support for complex integration in real project. So, it maps the basic structure of a program so that each independent layer can register its own oplists independently of the others, and only the final integrator maps everything together.

 ```C
