# Makefile.head -- the initial portion of a generic makefile
# framework to be included at the top directory of each component. 
#
# Before including this file, the TOP variable should be set to the
# absolute path of the top-level project directory, and the COMP
# variable should be set to the path to the component's top-level
# directory, relative to the project's top-level directory.  After
# including this file, include the directory makefiles, and then
# include Makefile.tail.  Before including Makefile.tail, TARGETS
# should be set to the default targets to be made when "make" is
# invoked with no arguments.  The target rules themselves can be
# declared after Makefile.tail in order to use variables such as OBJS
# which are set in Makefile.tail.
#
# WARNING: These makefiles will not work if you have spaces in any
# pathnames, including any parent directory outside the project
# hierarchy.  This is a limitation of GNU make (quoting things
# doesn't help).  Sorry.
#
# The makefiles also probably won't work very well if the component
# directory is a symlink, and the top-level directory is the symbolic
# parent (i.e. dirname `pwd -L`) rather than the physical parent
# (i.e. dirname `pwd -P`).
#
# NOTE: due to suckage of make that I haven't figured out how to work
# around, you'll have to run make twice after you update a .cdl file
# in order to make sure that any code that includes the generated
# headers has been rebuilt.  This is despite having an explicit
# dependency of the .cc file on the normal .h, of the normal .h on
# the generated .h, of the generated headers on the server directory,
# and of the server directory on the CDL file.  The CDL->directory
# rule is used to generated the headers, but even if it's done
# specifically for the .cc file up the chain, it doesn't rebuild the
# .cc file.
