-?AMDEP?@AMDEP@%FPFX%DEPMODE = @%FPFX%DEPMODE@
+## Note it is on purpose we wrote `if %AMDEP%', since:
+##
+## - if deps are turned off, %AMDEP% is mapped onto FALSE, and therefore
+## the `if FALSE' chunk is removed (automake-time conditionals).
+##
+## - if deps are on, %AMDEP% is mapped onto AMDEP, and therefore
+## the `if AMDEP' chunk is prefix with @AMDEP_TRUE@ just like for any
+## other configure-time conditional.
+##
+## We do likewise for %FASTDEP%; this expands to an ordinary
+## configure-time conditional. %FASTDEP% is used to speed up the
+## common case of building a package with gcc 3.x. In this case we
+## can skip the use of depcomp and easily inline the dependency
+## tracking.
+## Verbosity of FASTDEP rules
+## --------------------------
+## (1) Some people want to see what happens during make. They think
+## @-commands are evil because hiding things hinders debugging.
+## (2) Other people want to see only the important commands--those that
+## may produce diagnostics, such as compiler invocations. They
+## do not care about build details such as dependency generation
+## (the if/then/else machinery in FASTDEP rules). Their point is
+## that it is hard to spot diagnostics in a verbose output.
+## (3) Other people want `make -s' to work as expected: silently.
+## This way they can spot any diagnostic really easily.
+##
+## The second point suggests we hide rules with @ and that we `echo'
+## only the relevant parts. However this goes against the two others.
+## There are regular complaints about this on the mailing list, but
+## it's hard to please everybody. On April 2003, William Fulton (from
+## clan (3)) and Karl Berry (from clan (2)) agreed that folding the
+## compile rules so that they are output on a single line (instead of 5)
+## would be a good compromise. Actually we use two lines rather than one,
+## because this way %SOURCE% is always located at the end of the first
+## line and is therefore easier to spot. (We need an extra line when
+## depbase is used.)
