""" Extract attachments from emails and store them as files.
    Command-line argument: target directory
    Stdin: email text (e.g., through procmail)
 
    This script performs no error checking and assumes that anything with
    a filename will be base64-encoded. This is really only meant to collect
    data that is emailed automatically. Test well and use at your own risk.
