-- Note on terminology --
-------------------------
-- In this program, we use the phrase "termination" of a file name to
-- refer to the suffix that appears after the unit name portion. Very

-- may be more complex, for example in main.1.ada, the termination in
-- this name is ".1.ada" and in main_.ada the termination is "_.ada".

-- Queue (Q) Manipulation Routines --
-------------------------------------
-- The Q is used in Compile_Sources below. Its implementation uses the
-- GNAT generic package Table (basically an extensible array). Q_Front
-- points to the first valid element in the Q, whereas Q.First is the first
-- element ever enqueued, while Q.Last - 1 is the last element in the Q.

-- After Compile_Sources has terminated its execution, Q_Front = Q.Last
