# OVERVIEW
#
#   SQLite Embedded Database
#
# NOTES
#
#   Please be warned that locks currently do nothing on Windows since
#   figuring out how to polyfill them correctly is a work in progress
#   Further note we currently don't do that thing SQLite does for Mac
#   file locks so your dbase will only be as reliable as Apple wanted
#   it to be when they wrote their POSIX file locking implementation.
