## Commentary:

# The ttn-do command is from:
#  <https://www.gnuvola.org/software/ttn-do/>
#
# The tidy command is from:
#  <https://github.com/htacg/tidy-html5/>
#
# Usage: make [RAW=1]
#
# If given ‘RAW=1’, bypass tidy.  Otherwise, the default is to
# generate the page and pipe it through tidy (with many options).

## Code:

RAW = 0

gen := ttn-do make-gnu-pkg-homepage

ifeq (1,$(RAW))
clean := cat
else
clean := { tidy -i				\
		--vertical-space yes		\
		--doctype omit			\
		--fix-style-tags no		\
		--omit-optional-tags yes	\
		--tidy-mark no ;		\
	   echo '</div></body></html>' ; }
