"""Sending emails for commits and branch changes.

To have bzr send an email you need to configure an address to send mail

to for that branch. To do this set the configuration option ``post_commit_to``

and the address to send the mail from is read from the configuration option

``post_commit_sender`` (if not supplied defaults to the email address reported

by ``bzr whoami``).

By default, the diff for the commit will be included in the email if the

length is less than 1000 lines. This limit can be changed by setting the

configuration option 'post_commit_difflimit' to the number of lines you wish

it to be limited to. Set it to 0 to unconditionally disable sending of diffs.

By default bzr-email only emails when a commit occurs, not when a push or

pull operation occurs. To email on push or pull set post_commit_push_pull=True

in the configuration.

If you are using a bzr release from before 0.15, you need to manually tell

bzr about the commit action, by setting

post_commit=breezy.plugins.email.post_commit in bazaar.conf or locations.conf.

The URL of the branch is determined from the following checks (in order):

 - If the configuration value 'post_commit_url' is set, it is used.

 - If the configuration value 'public_branch' is set, it is used.

 - The URL of the branch itself.

Setting public_branch is highly recommended if you commit via a protocol which

has a private address (e.g. bzr+ssh but anonymous access might be bzr:// or

http://).

How emails are sent is determined by the value of the configuration option

'post_commit_mailer':

 - Unset: use ``/usr/bin/mail``.

 - ``smtplib``: Use python's smtplib to send the mail. If you use 'smtplib' you

   can also configure the settings "smtp_server=host[:port]",

   "smtp_username=userid", "smtp_password". If "smtp_username" is set but

   "smtp_password" is not, you will be prompted for a password.

   Also, if using 'smtplib', the messages will be sent as a UTF-8 text message,

   with a 8-bit text diff attached (rather than all-as-one). Work has also been

   done to make sure usernames do not have to be ascii.

 - Any other value: Run the value expecting it to behave like ``/usr/bin/mail``

   - in particular supporting the -s and -a options.

When using smtplib, you can specify additional headers to be included in the

mail by setting the 'revision_mail_headers' configuration option - something

like::

  revision_mail_headers=X-Cheese: to the rescue!
