88 -- Note on terminology --
89 -------------------------
91 -- In this program, we use the phrase "termination" of a file name to
92 -- refer to the suffix that appears after the unit name portion. Very
93 -- often this is simply the extension, but in some cases, the sequence
94 -- may be more complex, for example in main.1.ada, the termination in
95 -- this name is ".1.ada" and in main_.ada the termination is "_.ada".

104 -- element ever enqueued, while Q.Last - 1 is the last element in the Q.
