-   institute patent litigation against any entity (including a
-   cross-claim or counterclaim in a lawsuit) alleging that the Work
-   or a Contribution incorporated within the Work constitutes direct
-   or contributory patent infringement, then any patent licenses
-   granted to You under this License for that Work shall terminate
-   as of the date such litigation is filed.
-
-4. Redistribution. You may reproduce and distribute copies of the
-   Work or Derivative Works thereof in any medium, with or without
-   modifications, and in Source or Object form, provided that You
-   meet the following conditions:
-
-   (a) You must give any other recipients of the Work or
-       Derivative Works a copy of this License; and

-       attribution notices from the Source form of the Work,
-       excluding those notices that do not pertain to any part of
-       the Derivative Works; and
-
-   (d) If the Work includes a "NOTICE" text file as part of its
-       distribution, then any Derivative Works that You distribute must
-       include a readable copy of the attribution notices contained
-       within such NOTICE file, excluding those notices that do not
-       pertain to any part of the Derivative Works, in at least one
-       of the following places: within a NOTICE text file distributed
-       as part of the Derivative Works; within the Source form or
-       documentation, if provided along with the Derivative Works; or,
-       within a display generated by the Derivative Works, if and
-       wherever such third-party notices normally appear. The contents
-       of the NOTICE file are for informational purposes only and
-       do not modify the License. You may add Your own attribution
-       notices within Derivative Works that You distribute, alongside
-       or as an addendum to the NOTICE text from the Work, provided

-       as modifying the License.
-
-   You may add Your own copyright statement to Your modifications and
-   may provide additional or different license terms and conditions

-5. Submission of Contributions. Unless You explicitly state otherwise,
-   any Contribution intentionally submitted for inclusion in the Work
-   by You to the Licensor shall be under the terms and conditions of

-   Notwithstanding the above, nothing herein shall supersede or modify
-   the terms of any separate license agreement you may have executed
-   with Licensor regarding such Contributions.
-
-6. Trademarks. This License does not grant permission to use the trade
-   names, trademarks, service marks, or product names of the Licensor,
-   except as required for reasonable and customary use in describing the
-   origin of the Work and reproducing the content of the NOTICE file.

-7. Disclaimer of Warranty. Unless required by applicable law or
-   agreed to in writing, Licensor provides the Work (and each

-   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-   implied, including, without limitation, any warranties or conditions
-   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-   PARTICULAR PURPOSE. You are solely responsible for determining the
-   appropriateness of using or redistributing the Work and assume any
-   risks associated with Your exercise of permissions under this License.
-
-8. Limitation of Liability. In no event and under no legal theory,
-   whether in tort (including negligence), contract, or otherwise,
-   unless required by applicable law (such as deliberate and grossly
-   negligent acts) or agreed to in writing, shall any Contributor be
-   liable to You for damages, including any direct, indirect, special,
-   incidental, or consequential damages of any character arising as a
-   result of this License or out of the use or inability to use the
-   Work (including but not limited to damages for loss of goodwill,
-   work stoppage, computer failure or malfunction, or any and all
-   other commercial damages or losses), even if such Contributor
-   has been advised of the possibility of such damages.
-
-9. Accepting Warranty or Additional Liability. While redistributing
-   the Work or Derivative Works thereof, You may choose to offer,
-   and charge a fee for, acceptance of support, warranty, indemnity,
-   or other liability obligations and/or rights consistent with this
-   License. However, in accepting such obligations, You may act only
-   on Your own behalf and on Your sole responsibility, not on behalf
-   of any other Contributor, and only if You agree to indemnify,
-   defend, and hold each Contributor harmless for any liability
-   incurred by, or claims asserted against, such Contributor by reason
-   of your accepting any such warranty or additional liability.

-
-# Encryption
-
-Messages SHOULD be encrypted by the
-[Autocrypt](https://autocrypt.org/level1.html) standard;
-`prefer-encrypt=mutual` MAY be set by default.
-
-Meta data (at least the subject and all chat-headers) SHOULD be encrypted
-by the [Memoryhole](https://github.com/autocrypt/memoryhole) standard.
-If Memoryhole is not used,
-the subject of encrypted messages SHOULD be replaced by the string
-`Chat: Encrypted message` where the part after the colon MAY be localized.
-
-
-# Outgoing messages
-
-Messengers MUST add a `Chat-Version: 1.0` header to outgoing messages.
-For filtering and smart appearance of the messages in normal MUAs,
-the `Subject` header SHOULD start with the characters `Chat:`
-and SHOULD be an excerpt of the message.
-Replies to messages MAY follow the typical `Re:`-format.
-
-The body MAY contain text which MUST have the content type `text/plain`
-or `mulipart/alternative` containing `text/plain`.
-
-The text MAY be divided into a user-text-part and a footer-part using the
-line `-- ` (minus, minus, space, lineend).
-
-The user-text-part MUST contain only user generated content.
-User generated content are eg. texts a user has actually typed
-or pasted or forwarded from another user.
-Full quotes, footers or sth. like that MUST NOT go to the user-text-part.
-
-    From: sender@domain
-    To: rcpt@domain
-    Chat-Version: 1.0
-    Content-Type: text/plain
-    Subject: Chat: Hello ...
-
-    Hello world!
-
-
-# Incoming messages
-
-The `Chat-Version` header MAY be used
-to detect if a messages comes from a compatible messenger.
-
-The `Subject` header MUST NOT be used
-to detect compatible messengers, groups or whatever.
-
-Messenger SHOULD show the `Subject`
-if the message comes from a normal MUA together with the email-body.
-The email-body SHOULD be converted
-to plain text, full-quotes and similar regions SHOULD be cut.
-
-Attachments SHOULD be shown where possible.
-If an attachment cannot be shown, a non-distracting warning SHOULD be printed.
-
-
-# Forwarded messages
-
-Forwarded messages are outgoing messages that contain a forwarded-header
-before the user generated content.
-
-The forwarded header MUST contain two lines: 
-The first line contains the text
-`---------- Forwarded message ----------`
-(10 minus, space, text `Forwarded message`, space, 10 minus). 
-The second line starts with `From: ` followed by the original sender
-which SHOULD be anonymized or just a placeholder.
-
-    From: sender@domain
-    To: rcpt@domain
-    Chat-Version: 1.0
-    Content-Type: text/plain
-    Subject: Chat: Forwarded message
-
-    ---------- Forwarded message ----------
-    From: Messenger
-
-    Hello world!
-
-Incoming forwarded messages are detected by the header.
-The messenger SHOULD mark these messages in a way that
-it becomes obvious that the message is not created by the sender.
-Note that most messengers do not show the original sender of forwarded messages
-but MUAs typically expose the sender in the UI.
-
-
-# Groups
-
-Groups are chats with usually more than one recipient,
-each defined by an email-address.
-The sender plus the recipients are the group members.
-
-To allow different groups with the same members,
-groups are identified by a group-id.
-The group-id MUST be created only from the characters
-`0`-`9`, `A`-`Z`, `a`-`z` `_` and `-`.
-
-Groups MUST have a group-name.
-The group-name is any non-zero-length UTF-8 string.
-
-Groups MAY have a group-image.
-
-
-## Outgoing groups messages
-
-All group members MUST be added to the `From`/`To` headers.
-The group-id MUST be written to the `Chat-Group-ID` header.
-The group-name MUST be written to `Chat-Group-Name` header
-(the forced presence of this header makes it easier
-to join a group chat on a second device any time).
-
-The `Subject` header of outgoing group messages
-SHOULD start with the characters `Chat:`
-followed by the group-name and a colon followed by an excerpt of the message.
-
-To identify the group-id on replies from normal MUAs,
-the group-id MUST also be added to the message-id of outgoing messages.
-The message-id MUST have the format `Gr.<group-id>.<unique data>`.
-
-    From: member1@domain
-    To: member2@domain, member3@domain
-    Chat-Version: 1.0
-    Chat-Group-ID: 1234xyZ
-    Chat-Group-Name: My Group
-    Message-ID: Gr.1234xyZ.0001@domain
-    Subject: Chat: My Group: Hello group ...
-
-    Hello group - this group contains three members
-
-Messengers adding the member list in the form `Name <email-address>`
-MUST take care only to spread the names authorized by the contacts themselves.
-Otherwise, names as _Daddy_ or _Honey_ may be spread
-(this issue is also true for normal MUAs, however,
-for more contact- and chat-centralized apps
-such situations happen more frequently).
-
-
-## Incoming group messages
-
-The messenger MUST search incoming messages for the group-id
-in the following headers: `Chat-Group-ID`,
-`Message-ID`, `In-Reply-To` and `References` (in this order).
-
-If the messenger finds a valid and existent group-id,
-the message SHOULD be assigned to the given group.
-If the messenger finds a valid but not existent group-id,
-the messenger MAY create a new group.
-If no group-id is found,
-the message MAY be assigned
-to a normal single-user chat with the email-address given in `From`.
-
-
-## Add and remove members
-
-Messenger clients MUST construct the member list
-from the `From`/`To` headers only on the first group message
-or if they see a `Chat-Group-Member-Added`
-or `Chat-Group-Member-Removed` action header.
-Both headers MUST have the email-address
-of the added or removed member as the value.
-Messenger clients MUST NOT construct the member list
-on other group messages
-(this is to avoid accidentally altered To-lists in normal MUAs;
-the user does not expect adding a user to a _message_
-will also add him to the _group_ "forever").
-
-The messenger SHOULD send an explicit mail for each added or removed member.
-The body of the message SHOULD contain
-a localized description about what happened
-and the message SHOULD appear as a message or action from the sender.

-
-To remove a member:
-
-    From: member1@domain
-    To: member2@domain, member3@domain
-    Chat-Version: 1.0
-    Chat-Group-ID: 1234xyZ

-    Subject: Chat: My Group: Hello, ...
-
-    Hello, I've removed member4@domain from our group.  Now we have 3 members.
-
-
-## Change group name
-
-To change the group-name,
-the messenger MUST send the action header `Chat-Group-Name-Changed`
-with the value set to the old group name to all group members.
-The new group name goes to the header `Chat-Group-Name`.
-
-The messenger SHOULD send an explicit mail for each name change.
-The body of the message SHOULD contain
-a localized description about what happened
-and the message SHOULD appear as a message or action from the sender.

-    Subject: Chat: Our Group: Hello, ...
-
-    Hello, I've changed the group name from "My Group" to "Our Group".
-
-
-## Set group image
-
-A group MAY have a group-image.
-To change or set the group-image,
-the messenger MUST attach an image file to a message
-and MUST add the header `Chat-Group-Image`
-with the value set to the image name.
-
-To remove the group-image,
-the messenger MUST add the header `Chat-Group-Image: 0`.
-
-The messenger SHOULD send an explicit mail for each group image change.
-The body of the message SHOULD contain
-a localized description about what happened
-and the message SHOULD appear as a message or action from the sender.

-
-The image format SHOULD be image/jpeg or image/png.
-To save data, it is RECOMMENDED
-to add a `Chat-Group-Image` only on image changes.
-
-
-# Set profile image
-
-A user MAY have a profile-image that MAY be spread to his contacts.
-To change or set the profile-image,
-the messenger MUST attach an image file to a message
-and MUST add the header `Chat-Profile-Image`
-with the value set to the image name.
-
-To remove the profile-image,
-the messenger MUST add the header `Chat-Profile-Image: 0`.
-
-To spread the image,
-the messenger MAY send the profile image
-together with the next mail to a given contact
-(to do this only once,
-the messenger has to keep a `profile_image_update_state` somewhere).
-Alternatively, the messenger MAY send an explicit mail
-for each profile-image change to all contacts using a compatible messenger.
-The messenger SHOULD NOT send an explicit mail to normal MUAs.

-Note that `Chat-Profile-Image` may appear together with all other headers,
-eg. there may be a `Chat-Profile-Image` and a `Chat-Group-Image` header
-in the same message.
-To save data, it is RECOMMENDED to add a `Chat-Profile-Image` header
-only on image changes.
-
-
-# Miscellaneous
-
-Messengers SHOULD use the header `Chat-Predecessor`
-instead of `In-Reply-To` as the latter one results
-in infinite threads on typical MUAs.
-
-Messengers SHOULD add a `Chat-Voice-message: 1` header
-if an attached audio file is a voice message.
-
-Messengers MAY add a `Chat-Duration` header
-to specify the duration of attached audio or video files.
-The value MUST be the duration in milliseconds.
-This allows the receiver to show the time without knowing the file format.
-
-    Chat-Predecessor: foo123@domain
-    Chat-Voice-Message: 1
-    Chat-Duration: 10000
-
-Messengers MAY send and receive Message Disposition Notifications
-(MDNs, [RFC 8098](https://tools.ietf.org/html/rfc8098),
-[RFC 3503](https://tools.ietf.org/html/rfc3503))
-using the `Chat-Disposition-Notification-To` header
-instead of the `Disposition-Notification-To`
-(which unfortunately forces many other MUAs
-to send weird mails not following any standard).
-
-
-## Sync messages
-
-If some action is required by a message header,
-the action should only be performed if the _effective date_ is newer
-than the date the last action was performed.
-
-We define the effective date of a message
-as the sending time of the message as indicated by its Date header,
-or the time of first receipt if that date is in the future or unavailable.
