# This script builds the PDF version of the PostgreSQL documentation.
#
# In principle we could do this as part of the RPM build, but there are
# good reasons not to:
# 1. The build would take longer and have a larger BuildRequires footprint.
# 2. The generated PDF has timestamps in it, which would inevitably result
#    in multilib conflicts due to slightly different timestamps.
# So instead, we run this manually when rebasing to a new upstream release,
# and treat the resulting PDF as a separate Source file.
#
# You will need to have the docbook packages installed to run this.
# Expect it to take about 20 minutes and use about 160MB of disk.
