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

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