        Next step is to create a book and build scripts in dependencies build order
     for a target package. A target can be a package or a meta-package.

+           selected on each configuration run.

        Run <make> to launch the configuration interface. The main menu contains
     three block: meta-package selection, individual package selection, and
     build options.
 
-       Only one meta-package or individual package must be selected on each run.
-    That is due that there is no way to solve dependencies properly when
-    more than one target are selected at the same time.
-
        When a meta-package is selected is possible to unselect unwanted components.
     That unselected components will be skipped if no other components depends
     on them.
