SQLite

#!/bin/sh
#
# This script demonstrates how to do a full-featured build of the sqlite3
# command-line shell on Linux.
#
# SQLite source code should be in a sibling directory named "sqlite".  For
# example, put SQLite sources in ~/sqlite/sqlite and run this script from
# ~/sqlite/bld.  There should be an appropriate Makefile in the current
# directory as well.
