# Standard variables and rules for building a general standalone document
# that doesn't fall into any partcular category (such as lecture, tutorial).
# The makefile assumes a single document source file. Anything more
# complex than this will need to be handled by a custom makefile.
#
# Altering these definitions will affect ALL MAKEFILES FOR ALL PAPERS!! If
# you need to do something specific for a particular paper, include a
# custom rule in its makefile. DON'T add it here!

# any platform with sensible path standards. Quoting the value doesn't

# Generate the derived XML source from the original XML template.
# This is done by simply running the original source through xmllint
# with the --xinclude option to process all the xi:include elements.
# The result of this could have just been piped into the XSLT processor,
# except that (a) not all of the processors support input from stdin,
# and (b) combining both xmllint and XSLT processing into one command
# means that make won't stop if there's any errors from xmllint.
#
# Sed is used to add a comment to the derived XML file, warning that this
# is generated and shouldn't be edited. Sed was used because the <?xml?>
# processing instruction MUST be on the first line. The implication here
# is that all input source files have an <?xml?> processing instruction
# (which they should anyway).
