# This script is used to build the amalgamation autoconf package.
# It assumes the following:
#
#   1. The files "sqlite3.c", "sqlite3.h", "sqlite3ext.h", "shell.c",
#      and "sqlite3rc.h" are available in the current directory.
#
#   2. Variable $TOP is set to the full path of the root directory
#      of the SQLite source tree.
#
#   3. There is nothing of value in the ./mkpkg_tmp_dir directory.
#      This is important, as the script executes "rm -rf ./mkpkg_tmp_dir".
#


# Bail out of the script if any command returns a non-zero exit
# status. Or if the script tries to use an unset variable. These
# may fail for old /bin/sh interpreters.
