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

98 -- Queue (Q) Manipulation Routines --
99 -------------------------------------
101 -- The Q is used in Compile_Sources below. Its implementation uses the
102 -- GNAT generic package Table (basically an extensible array). Q_Front
103 -- points to the first valid element in the Q, whereas Q.First is the first
104 -- element ever enqueued, while Q.Last - 1 is the last element in the Q.

117 -- and the elements contained between Q.Front and Q.Last-1 are those that
