scattered. The default is
- Host name to which the local development server's administration console should bind (default: localhost).
- Port to which the local development server's administration console should bind (default: 8000).
- Clears the datastore data and history files before starting the web server.

- Uses the local computer's Sendmail installation for sending email messages.
- Prints a helpful message then quits.

- The port number of the SMTP server to use for sending email messages.
- The username to use with the SMTP server for sending email messages.
- The password to use with the SMTP server for sending email messages.

Blobstore, Cloud Storage files and logs, will be stored, unless
- Path to the php-cgi binary.
