===========
Changed some internal symbol names so they won't clash with similar
new ones used by SQLite in the amalgamation.
Added :attr:`apsw.using_amalgamation` so you can tell if APSW was
compiled using the `SQLite amalgamation
<https://sqlite.org/cvstrac/wiki?p=TheAmalgamation>`__. Using the
amalgamation means that SQLite shared libraries are not used and will
not affect your code.
Added a checksums file so that when :file:`setup.py` downloads SQLite,
we know it hasn't been tampered with. (The :ref:`--fetch-sqlite
<setup_py_flags>` argument can be used to automatically download
SQLite.)
