// An xpcshell script to create a test database.  Useful for creating
// the test-env-32 and test-env-64 databases that we use to test migration
// of databases across architecture changes.
//
// To create a test database, simply run this script using xpcshell:
//
//   path/to/xpcshell path/to/make-test-env.js
//
// The script will create the test-env-32 or test-env-64 directory
// (depending on the current architecture) in the current working directory,
// create a database called "db" within it, and populate the database
// with sample data.
//
// Note: you don't necessarily need to run this script on every architecture
// for which you'd like to create a database.  Once you have a database for one
// architecture, you can use the mdb_dump and mdb_load utilities (if available
// for your systems) to create them for others.  To do so, first dump the data
// on the original architecture:
//
//   mdb_dump -s db path/to/original/test-env-dir > path/to/dump.txt
//
// Then load the data on the new architecture:
//
//   mkdir path/to/new/test-env-dir
//   mdb_load -s db path/to/dump.txt
