# Template makefile for building a particular content file for a document.
# Place a copy of this file in the directory containing the content file,
# and modify as appropriate. The makefile should be called with the name
# of a specific content file as target. It will then check whether there
# are any prerequisites to that file that may have changed, and rebuild
# them if necessary.Most of the work is done by the include files, and
# should cater for almost all cases. However, if custom rules are needed
# for a section, they can be appended to the end of the document's
# makefile.
#
# Note that the ONLY mode of operation for this makefile is to be called
# from the makefile for a particular document, with the name of a specific
# content file as the target. This makefile cannot be easily executed
# standalone! This is because the content directory can exist at a
# relatively arbitrary location within the paper's directory hierarchy. We
# therefore don't know where to look, relative to the current directory,
# to find the local include directory, and thus cannot provide a
# meaningful value for the variable LOCAL_HANDBOOK_INCLUDE. The value of
# LOCAL_HANDBOOK_INCLUDE must therefore be passed in from the calling
# environment.
