################################################################################
# vlc (VideoLAN Client) dependencies makefile
# (c)1998 VideoLAN
################################################################################
# This Makefile is dedicated to build of .d files. It should not be called
# directly by user, but only through main Makefile.
################################################################################
###############################################################################
# Note on generic rules and dependencies
###############################################################################
# Note on dependencies: each .c file is associated with a .d file, which
# depends of it. The .o file associated with a .c file depends of the .d, of the
# .c itself, and of Makefile. The .d files are stored in a separate .dep/
# directory.
# The dep directory should be ignored by CVS.
# Note on inclusions: depending of the target, the dependencies files must
# or must not be included. The problem is that if we ask make to include a file,
# and this file does not exist, it is made before it can be included. In a
# general way, a .d file should be included if and only if the corresponding .o
# needs to be re-made.
# The object Makefile knows how to make a .o from a .c, and includes
# dependencies for the target, but only those required.
# All settings and options are passed through main Makefile
################################################################################
# Default target

@echo "This Makefile should not be called directly,"

################################################################################
# Dependencies creation
################################################################################
# A dependencies file needs to be rebuilt if the .c changed or if one of the
# dependencies files have been changed. In other words, it depends from the
# .c and from itself.
