The ccmakedep program calls a C compiler to preprocess each sourcefile,
and uses the output to construct makefile rules describing their depen-
dencies. These rules instruct make(1) on which object files must be
recompiled when a dependency has changed.
By default, ccmakedep places its output in the file named makefile if
it exists, otherwise Makefile. An alternate makefile may be specified
with the -f option. It first searches the makefile for a line begin-
# DO NOT DELETE
or one provided with the -s option, as a delimiter for the dependency
output. If it finds it, it will delete everything following this up to
the end of the makefile and put the output after this line. If it
doesn't find it, the program will append the string to the makefile and
place the output after that.
Normally, ccmakedep will be used in a makefile target so that typing
'make depend' will bring the dependencies up to date for the makefile.

The program will ignore any option that it does not understand, so you
may use the same arguments that you would for cc(1), including -D and
-U options to define and undefine symbols and -I to set the include

Filename. This allows you to specify an alternate makefile in
which ccmakedep can place its output. Specifying "-" as the
file name (that is, -f-) sends the output to standard output
instead of modifying an existing file.

still processed normally.
