#
# This contains targets to build the website and add the documentation generated from the Cassandra source.
#
# The add-doc command build the document from the cassandra sources pointed by the CASSANDRA_DIR environment variable
# and copy it in doc/<version>/. The add-latest-doc does the same but also create/modify the doc/latest symlink so it
# points to the doc it just created (so to use to replace the "current" documentation).
#
# Note that the add-doc and add-latest-doc are not called automatically from other targets and needs to be called
# manually. That's because there is many cases where you want to just update the website, without reconstructing the
# documentation. Note however that the doc target do rebuild the website.
