#
# (The semicolons are here for clarification, but of course are not
# emitted.) This is what Autoconf 2.0 (I think) to 2.13 (I'm sure)
#
# The dependencies between the macros are:
#
-# 3 --- 2b
-# / \ is m4_require'd by
-# / \ left -------------------- right
-# 2a ------------ 1
+# 3 --- 2b
+# / \ is m4_require'd by
+# / \ left -------------------- right
+# 2a ------------ 1
#
# If you strictly apply the rules given in the previous section you get:
#
-# GROW - 2: TEST3
-# GROW - 1: TEST2a; TEST2b
-# GROW: TEST1
-# BODY:
+# GROW - 2: TEST3
+# GROW - 1: TEST2a; TEST2b
+# GROW: TEST1
+# BODY:
#
# (TEST2a, although required by TEST3 is not expanded in GROW - 3
# because is has already been expanded before in GROW - 1, so it has
# been AC_PROVIDE'd, so it is not expanded again) so when you undivert
# the stack of diversions, you get:
#
-# GROW - 2:
-# GROW - 1:
-# GROW:
-# BODY: TEST3; TEST2a; TEST2b; TEST1
+# GROW - 2:
+# GROW - 1:
+# GROW:
+# BODY: TEST3; TEST2a; TEST2b; TEST1
#
# i.e., TEST2a is expanded after TEST3 although the latter required the
# former.
# In the example above, when TEST2a is expanded, but it's epilogue is
# not run yet, you have:
#
-# GROW - 2:
-# GROW - 1: TEST2a
-# GROW: Elaboration of TEST1
-# BODY:
+# GROW - 2:
+# GROW - 1: TEST2a
+# GROW: Elaboration of TEST1
+# BODY:
#
# The epilogue of TEST2a emits it immediately:
#
-# GROW - 2:
-# GROW - 1:
-# GROW: Elaboration of TEST1
-# BODY: TEST2a
+# GROW - 2:
+# GROW - 1:
+# GROW: Elaboration of TEST1
+# BODY: TEST2a
#
# TEST2b then requires TEST3, so right before the epilogue of TEST3, you
# have:
#
-# GROW - 2: TEST3
-# GROW - 1: Elaboration of TEST2b
-# GROW: Elaboration of TEST1
-# BODY: TEST2a
+# GROW - 2: TEST3
+# GROW - 1: Elaboration of TEST2b
+# GROW: Elaboration of TEST1
+# BODY: TEST2a
#
# The epilogue of TEST3 emits it:
#
-# GROW - 2:
-# GROW - 1: Elaboration of TEST2b
-# GROW: Elaboration of TEST1
-# BODY: TEST2a; TEST3
+# GROW - 2:
+# GROW - 1: Elaboration of TEST2b
+# GROW: Elaboration of TEST1
+# BODY: TEST2a; TEST3
#
# TEST2b is now completely expanded, and emitted:
#
-# GROW - 2:
-# GROW - 1:
-# GROW: Elaboration of TEST1
-# BODY: TEST2a; TEST3; TEST2b
+# GROW - 2:
+# GROW - 1:
+# GROW: Elaboration of TEST1
+# BODY: TEST2a; TEST3; TEST2b
#
# and finally, TEST1 is finished and emitted:
#
-# GROW - 2:
-# GROW - 1:
-# GROW:
-# BODY: TEST2a; TEST3; TEST2b: TEST1
+# GROW - 2:
+# GROW - 1:
+# GROW:
+# BODY: TEST2a; TEST3; TEST2b: TEST1
