make: -w Option
5.7.4 The '--print-directory' Option
------------------------------------
If you use several levels of recursive 'make' invocations, the '-w' or
'--print-directory' option can make the output a lot easier to
understand by showing each directory as 'make' starts processing it and
as 'make' finishes processing it. For example, if 'make -w' is run in
the directory '/u/gnu/make', 'make' will print a line of the form:
make: Entering directory `/u/gnu/make'.
before doing anything else, and a line of the form:
make: Leaving directory `/u/gnu/make'.
when processing is completed.
Normally, you do not need to specify this option because 'make' does
it for you: '-w' is turned on automatically when you use the '-C'
option, and in sub-'make's. 'make' will not automatically turn on '-w'
if you also use '-s', which says to be silent, or if you use
'--no-print-directory' to explicitly disable it.
