-------------------------
-- 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
-- often this is simply the extension, but in some cases, the sequence
-- 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.
--

-- Q.First Q_Front Q.Last - 1
--
-- The elements comprised between Q.First and Q_Front - 1 are the
-- elements that have been enqueued and then dequeued, while the
-- elements between Q_Front and Q.Last - 1 are the elements currently
-- in the Q. When the Q is initialized Q_Front = Q.First = Q.Last.
-- After Compile_Sources has terminated its execution, Q_Front = Q.Last
-- and the elements contained between Q.Front and Q.Last-1 are those that
-- were explored and thus marked by Compile_Sources. Whenever the Q is
-- reinitialized, the elements between Q.First and Q.Last - 1 are unmarked.
