- -- 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.

- -- 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.
