 I believe if you create a child library of a generic package (pardon
my butchering of the terminology, I'm new to Ada 95), the child itself
must also be generic.  Oftentimes, the child won't need a generic
parameter of its own, only needing that of its parent, in which case
you'd get the interesting construct:

generic
package Blah is...

 This is covered in "Programming in Ada 95" by John Barnes, page 390.
