#                                 Makefile.common
#
# This file is included by all of the LLVM makefiles.  This file defines common
# rules to do things like compile a .cpp file or generate dependancy info.
# These are platform dependant, so this is the file used to specify these
# system dependant operations.
#
# The following functionality may be set by setting incoming variables:
#
# 1. LEVEL - The level of the current subdirectory from the top of the 
#    MagicStats view.  This level should be expressed as a path, for 
#    example, ../.. for two levels deep.
#
# 2. DIRS - A list of subdirectories to be built.  Fake targets are set up
#    so that each of the targets "all", "install", and "clean" each build.
#    the subdirectories before the local target.
#
# 3. Source - If specified, this sets the source code filenames.  If this
#    is not set, it defaults to be all of the .cpp, .c, .y, and .l files 
#    in the current directory.  Also, if you want to build files in addition
#    to the local files, you can use the ExtraSource variable
#

# Default Rule:  Make sure it's also a :: rule
all ::

# Default for install is to at least build everything...
