# PostGIS documentation build Makefile

# Written by Mark Cave-Ayland

# NOTE: We don't use a standard PGXS Makefile here since the DOCS target
# only allows files to be stored within contrib/ and we currently
# store documentation under contrib/postgis due to the possibility
# that we could produce a large number of files (think chunked HTML)
