89 -- Note on terminology --
90 -------------------------
92 -- In this program, we use the phrase "termination" of a file name to
93 -- refer to the suffix that appears after the unit name portion. Very
94 -- often this is simply the extension, but in some cases, the sequence
95 -- may be more complex, for example in main.1.ada, the termination in
96 -- this name is ".1.ada" and in main_.ada the termination is "_.ada".

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