# Makefile for DBCOURSES handbooks. Revamped completely from old
# monolithic version to a "many-makefiles" model. Each major sub-unit of
# the handbook has its own makefile, and is called recursively from here.
# This makes management of the whole process a bit more complex, but a lot
# more flexible. It's now possible, for example, to build many of the
# files for a single tutorial by going into that tutorial's directory and
# running a make there. The old scheme was also wont to rebuild lots of
# extraneous stuff when only one file changed (especially with graphics).
# This does not appear to be (and should not) be a problem with the new
# scheme.

# Required Environment Variables
#
# TEACHING_SHARED
# This variable specifies the path to the top level of the teaching
# shared directory hierarchy (e.g., /path/to/Teaching/Shared).
#
TEACHING_SHARED?=$(error The required environment variable TEACHING_SHARED has not been defined. It should point to the root level of the shared teaching directory (e.g., /path/to/Teaching/Shared))
#
# ALL_PAPERS_ROOT
# This variable specifies the path to the top level directory for all
# papers taught, i.e., the directory that contains the individual paper
# directory hierarchies. For example, /path/to/Teaching/2005.
#
ALL_PAPERS_ROOT?=$(error The required environment variable ALL_PAPERS_ROOT has not been defined. It should point to the root level of the current teaching directory hierarchy (e.g., /path/to/Teaching/2005))
#
# HANDBOOK_INSTALL_ROOT
# This variable specifies the path to the top level directory on the web
# server, under which the files for this paper will be installed (that is,
# the directory that contains the individual paper directory hierarchies).
# For example, \\INFO-NTS-12\DBCourses$ (this may require munging).
#
HANDBOOK_INSTALL_ROOT?=$(error The required environment variable HANDBOOK_INSTALL_ROOT has not been defined. It should point to the root level of the directory hierarchy on the web server (e.g., \\INFO-NTS-12\DBCourses$))

# Set up paths to makefile include directories.
#
# GLOBAL_HANDBOOK_INCLUDE is the global include directory in the "Shared"
# hierarchy, and is defined relative to the root of that hierarchy.
#
# LOCAL_HANDBOOK_INCLUDE is the local include directory for this
# particular paper, and is defined relative to the current execution
# directory. We are assuming a fixed directory structure here! We can't
# really do this as an environment variable because the full path will be
# different for each paper, and we can't use the variables from
# paper_variables.make to set the path, because that file is in the
# include directory! <head spins> We will, however, allow for the
# possibility of someone wanting to define this as an environment variable
# by making it a conditional assignment.
