# This script updates SQLite source files with a SQLite tarball.  The tarball is
# downloaded from the sqlite website.

# Usage: UPDATE-SOURCE.bash [-nF] <year> <sqlite-release>
#
# This script must be executed in $ANDROID_BUILD_TOP/external/sqlite/.  However,
# for testing it can run anywhere: use the -F switch.
