# The following will be generated or updated…
# …for every build (target 'doc.auto'):
# • user guide and man pages: if BUILD_DOCS is set
# • HTML versions of the above: if BUILD_DOCS and BUILD_WEB_DOCS are set
#
# …only when the 'doc' target is built explicitly:
# • Doxygen / reference documentation: if USE_DOXYGEN is set
