 * Write emails to disk. Output is written to ./.mail_output/<email type>.html
 *
 * Usage:
 * node ./scripts/write-to-disk.js <email type>
 *
 * Where <email type> is one of:
 *   all
 *   newDeviceLoginEmail
 *   passwordChangedEmail
 *   passwordResetEmail
 *   passwordResetRequiredEmail
 *   postVerifyEmail
 *   postVerifySecondaryEmail
 *   recoveryEmail
 *   unblockCodeEmail
 *   verificationReminderEmail:first
 *   verificationReminderEmail:second
 *   verifyEmail
 *   verifySecondaryEmail
 *   verifyLoginEmail
 *   verifyLoginCodeEmail
 *
 * Emails that are written to disk can be previewed in Firefox
 * to give a rough idea of how they would render in real life.
