# DOCBOOK_OUTPUT_FORMATS is the default set of targets (output
# formats) that get built when you type "make" without any targets
# explicitly specified. To generate a different set of output
# formats, change the value of DOCBOOK_OUTPUT_FORMATS here or set
# it in your environment; for example:
#
#   set DOCBOOK_OUTPUT_FORMATS="html pdf"; export DOCBOOK_OUTPUT_FORMATS
#
# Of course by explicitly specifying particular targets when you
# invoke "make", you can always override generation of the default
# set of targets; for example:
#
#   make html txt
#
# That would generate just HTML (unchunked) and plain-text output.
#
DOCBOOK_OUTPUT_FORMATS ?= man chunk txt pdf

# If you want XHTML output instead of HTML, set HTML_OR_XHTML to
# 'xhtml' or just specify 'xhtml" in DOCBOOK_OUTPUT_FORMATS.
