#
# Targets intended for use on the command line
#
# all (default)	-	generate the books TOC and compile all the documentation
# clean		- 	removes generated files
# run		-	serves the built documentation site for local browsing
# pdf		-	build PDF versions of the articles and books.
# html		-	build HTML versions of the articles and books for
#			offline use.
#			If variable DOC_HTML_ARCHIVE is set, all documents will be
#			archived/compressed, and only these files will be kept in the public
#			directory.
# epub		-	build EPUB versions of the articles and books (Experimental).
#
# The run target uses hugo's built-in webserver to make the documentation site
# available for local browsing.  The documentation should have been built prior
# to attempting to use the `run` target.  By default, hugo will start its
# webserver on port 1313.
