# Ability to build with system libsqlite3.
#
# Note that unless libsqlite3 on your system was built with an increased
# SQLITE_MAX_ATTACHED value (the default is 10), you will most likely come to
# regret using the system version.
#
# Also, while most distributions have to build libsqlite3 in a multi-threaded
# configuration, we build it single-threaded (and with disabled shared cache
# support), which gives us a non-negligible performance boost.
#

# be there unless the module is configured).
