"""Send the contents of a directory as a MIME message.
|
||
|
|
|
||
|
|
Usage: dirmail [options] from to [to ...]*
|
||
|
|
|
||
|
|
Options:
|
||
|
|
-h / --help
|
||
|
|
Print this message and exit.
|
||
|
|
|
||
|
|
-d directory
|
||
|
|
--directory=directory
|
||
|
|
Mail the contents of the specified directory, otherwise use the
|
||
|
|
current directory. Only the regular files in the directory are sent,
|
||
|
|
and we don't recurse to subdirectories.
|
||
|
|
|
||
|
|
`from' is the email address of the sender of the message.
|
||
|
|
|
||
|
|
`to' is the email address of the recipient of the message, and multiple
|
||
|
|
recipients may be given.
|
||
|
|
|
||
|
|
The email is sent by forwarding to your local SMTP server, which then does the
|
||
|
|
normal delivery process. Your local machine must be running an SMTP server.
