email_mirror: Use internal_send_message instead of the API

Previously, the email mirror queue worker used the API bindings to send messages to Zulip, as if it were any other API client. This is inefficient since we're running the worker inside the Django context on a machine with database access; we can instead just use the internal message-sending functions we use elsewhere. This also resolves potential issues with SSL certificates, etc. that might occur when we were previously making a HTTPS connection. (imported from commit 3f0d200eec66d926a8c6b3b33b825ac5d0edfe12)

-# Quick format and style primer:

-#  * If a pattern is meant only for a specific location, it should have a

-#    * In principle any non-trailing slash (like `zproject/dev-secrets.conf`)
-#      will do, but this makes a confusing pattern.  Adding a leading slash

-# Zulip Code of Conduct
-
-Like the technical community as a whole, the Zulip team and community is
-made up of a mixture of professionals and volunteers from all over the
-world, working on every aspect of the mission, including mentorship,
-teaching, and connecting people.
-
-Diversity is one of our huge strengths, but it can also lead to
-communication issues and unhappiness. To that end, we have a few ground
-rules that we ask people to adhere to. This code applies equally to
-founders, mentors, and those seeking help and guidance.
-
-This isn't an exhaustive list of things that you can't do. Rather, take it
-in the spirit in which it's intended --- a guide to make it easier to enrich
-all of us and the technical communities in which we participate.
-
-## Expected behavior
-
-The following behaviors are expected and requested of all community members:
-
-* Participate. In doing so, you contribute to the health and longevity of
-  the community.
-* Exercise consideration and respect in your speech and actions.
-* Attempt collaboration before conflict. Assume good faith.
-* Refrain from demeaning, discriminatory, or harassing behavior and speech.
-* Take action or alert community leaders if you notice a dangerous
-  situation, someone in distress, or violations of this code, even if they
-  seem inconsequential.
-* Community event venues may be shared with members of the public; be
-  respectful to all patrons of these locations.
-
-## Unacceptable behavior
-
-The following behaviors are considered harassment and are unacceptable
-within the Zulip community:
-
-* Jokes or derogatory language that singles out members of any race,
-  ethnicity, culture, national origin, color, immigration status, social and
-  economic class, educational level, language proficiency, sex, sexual
-  orientation, gender identity and expression, age, size, family status,
-  political belief, religion, and mental and physical ability.
-* Violence, threats of violence, or violent language directed against
-  another person.
-* Disseminating or threatening to disseminate another person's personal
-  information.
-* Personal insults of any sort.
-* Posting or displaying sexually explicit or violent material.
-* Inappropriate photography or recording.
-* Deliberate intimidation, stalking, or following (online or in person).
-* Unwelcome sexual attention. This includes sexualized comments or jokes,
-  inappropriate touching or groping, and unwelcomed sexual advances.
-* Sustained disruption of community events, including talks and
-  presentations.
-* Advocating for, or encouraging, any of the behaviors above.
-
-## Reporting and enforcement
-
-Harassment and other code of conduct violations reduce the value of the
-community for everyone. If someone makes you or anyone else feel unsafe or
-unwelcome, please report it to the community organizers at
-zulip-code-of-conduct@googlegroups.com as soon as possible. You can make a
-report either personally or anonymously.
-
-If a community member engages in unacceptable behavior, the community
-organizers may take any action they deem appropriate, up to and including a
-temporary ban or permanent expulsion from the community without warning (and
-without refund in the case of a paid event).
-
-If someone outside the development community (e.g. a user of the Zulip
-software) engages in unacceptable behavior that affects someone in the
-community, we still want to know. Even if we don't have direct control over
-the violator, the community organizers can still support the people
-affected, reduce the chance of a similar violation in the future, and take
-any direct action we can.
-
-The nature of reporting means it can only help after the fact. If you see
-something you can do while a violation is happening, do it. A lot of the
-harms of harassment and other violations can be mitigated by the victim
-knowing that the other people present are on their side.
-
-All reports will be kept confidential. In some cases, we may determine that a
-public statement will need to be made. In such cases, the identities of all
-victims and reporters will remain confidential unless those individuals
-instruct us otherwise.
-
-## Scope
-
-We expect all community participants (contributors, paid or otherwise,
-sponsors, and other guests) to abide by this Code of Conduct in all
-community venues, online and in-person, as well as in all private
-communications pertaining to community business.
-
-This Code of Conduct and its related procedures also applies to unacceptable
-behavior occurring outside the scope of community activities when such
-behavior has the potential to adversely affect the safety and well-being of
-community members.
-
-## License and attribution
-
-This Code of Conduct is adapted from the
-[Citizen Code of Conduct](http://citizencodeofconduct.org/) and the
-[Django Code of Conduct](https://www.djangoproject.com/conduct/), and is

-# Contributing to Zulip
-
-Welcome to the Zulip community!
-
-## Community
-
-The
-[Zulip community server](https://zulip.readthedocs.io/en/latest/contributing/chat-zulip-org.html)
-is the primary communication forum for the Zulip community. It is a good
-place to start whether you have a question, are a new contributor, are a new
-user, or anything else. Make sure to read the
-[community norms](https://zulip.readthedocs.io/en/latest/contributing/chat-zulip-org.html#community-norms)
-before posting. The Zulip community is also governed by a
-[code of conduct](https://zulip.readthedocs.io/en/latest/code-of-conduct.html).
-
-You can subscribe to
-[zulip-devel-announce@googlegroups.com](https://groups.google.com/g/zulip-devel-announce)
-or our [Twitter](https://twitter.com/zulip) account for a very low
-traffic (<1 email/month) way to hear about things like mentorship
-opportunities with Google Summer of Code, in-person sprints at
-conferences, and other opportunities to contribute.
-
-## Ways to contribute
-
-To make a code or documentation contribution, read our
-[step-by-step guide](#your-first-codebase-contribution) to getting
-started with the Zulip codebase. A small sample of the type of work that
-needs doing:
-* Bug squashing and feature development on our Python/Django
-  [backend](https://github.com/zulip/zulip), web
-  [frontend](https://github.com/zulip/zulip), React Native
-  [mobile app](https://github.com/zulip/zulip-mobile), or Electron
-  [desktop app](https://github.com/zulip/zulip-desktop).
-* Building out our
-  [Python API and bots](https://github.com/zulip/python-zulip-api) framework.
-* [Writing an integration](https://zulip.com/api/integrations-overview).
-* Improving our [user](https://zulip.com/help/) or
-  [developer](https://zulip.readthedocs.io/en/latest/) documentation.
-* [Reviewing code](https://zulip.readthedocs.io/en/latest/contributing/code-reviewing.html)
-  and manually testing pull requests.
-
-**Non-code contributions**: Some of the most valuable ways to contribute
-don't require touching the codebase at all. We list a few of them below:
-
-* [Reporting issues](#reporting-issues), including both feature requests and
-  bug reports.
-* [Giving feedback](#user-feedback) if you are evaluating or using Zulip.
-* [Translating](https://zulip.readthedocs.io/en/latest/translating/translating.html)
-  Zulip.
-* [Outreach](#zulip-outreach): Star us on GitHub, upvote us
-  on product comparison sites, or write for [the Zulip blog](https://blog.zulip.org/).
-
-## Your first (codebase) contribution
-
-This section has a step by step guide to starting as a Zulip codebase
-contributor. It's long, but don't worry about doing all the steps perfectly;
-no one gets it right the first time, and there are a lot of people available
-to help.
-* First, make an account on the
-  [Zulip community server](https://zulip.readthedocs.io/en/latest/contributing/chat-zulip-org.html),
-  paying special attention to the community norms. If you'd like, introduce
-  yourself in
-  [#new members](https://chat.zulip.org/#narrow/stream/95-new-members), using
-  your name as the topic. Bonus: tell us about your first impressions of
-  Zulip, and anything that felt confusing/broken as you started using the
-  product.
-* Read [What makes a great Zulip contributor](#what-makes-a-great-zulip-contributor).
-* [Install the development environment](https://zulip.readthedocs.io/en/latest/development/overview.html),
-  getting help in
-  [#development help](https://chat.zulip.org/#narrow/stream/49-development-help)
-  if you run into any troubles.
-* Read the
-  [Zulip guide to Git](https://zulip.readthedocs.io/en/latest/git/index.html)
-  and do the Git tutorial (coming soon) if you are unfamiliar with
-  Git, getting help in
-  [#git help](https://chat.zulip.org/#narrow/stream/44-git-help) if
-  you run into any troubles.  Be sure to check out the
-  [extremely useful Zulip-specific tools page](https://zulip.readthedocs.io/en/latest/git/zulip-tools.html).
-
-### Picking an issue
-
-Now, you're ready to pick your first issue! There are hundreds of open issues
-in the main codebase alone. This section will help you find an issue to work
-on.
-
-* If you're interested in
-  [mobile](https://github.com/zulip/zulip-mobile/issues?q=is%3Aopen+is%3Aissue),
-  [desktop](https://github.com/zulip/zulip-desktop/issues?q=is%3Aopen+is%3Aissue),
-  or
-  [bots](https://github.com/zulip/python-zulip-api/issues?q=is%3Aopen+is%3Aissue)
-  development, check the respective links for open issues, or post in
-  [#mobile](https://chat.zulip.org/#narrow/stream/48-mobile),
-  [#desktop](https://chat.zulip.org/#narrow/stream/16-desktop), or
-  [#integration](https://chat.zulip.org/#narrow/stream/127-integrations).
-* For the main server and web repository, we recommend browsing
-  recently opened issues to look for issues you are confident you can
-  fix correctly in a way that clearly communicates why your changes
-  are the correct fix.  Our GitHub workflow bot, zulipbot, limits
-  users who have 0 commits merged to claiming a single issue labeled
-  with "good first issue" or "help wanted".
-* We also partition all of our issues in the main repo into areas like
-  admin, compose, emoji, hotkeys, i18n, onboarding, search, etc. Look
-  through our [list of labels](https://github.com/zulip/zulip/labels), and
-  click on some of the `area:` labels to see all the issues related to your
-  areas of interest.
-* If the lists of issues are overwhelming, post in
-  [#new members](https://chat.zulip.org/#narrow/stream/95-new-members) with a
-  bit about your background and interests, and we'll help you out. The most
-  important thing to say is whether you're looking for a backend (Python),
-  frontend (JavaScript and TypeScript), mobile (React Native), desktop (Electron),
-  documentation (English) or visual design (JavaScript/TypeScript + CSS) issue, and a
-  bit about your programming experience and available time.
-
-We also welcome suggestions of features that you feel would be valuable or
-changes that you feel would make Zulip a better open source project. If you
-have a new feature you'd like to add, we recommend you start by posting in
-[#new members](https://chat.zulip.org/#narrow/stream/95-new-members) with the
-feature idea and the problem that you're hoping to solve.
-
-Other notes:
-* For a first pull request, it's better to aim for a smaller contribution
-  than a bigger one. Many first contributions have fewer than 10 lines of
-  changes (not counting changes to tests).
-* The full list of issues explicitly looking for a contributor can be
-  found with the
-  [good first issue](https://github.com/zulip/zulip/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22)
-  and
-  [help wanted](https://github.com/zulip/zulip/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22)
-  labels.  Avoid issues with the "difficult" label unless you
-  understand why it is difficult and are confident you can resolve the
-  issue correctly and completely.  Issues without one of these labels
-  are fair game if Tim has written a clear technical design proposal
-  in the issue, or it is a bug that you can reproduce and you are
-  confident you can fix the issue correctly.
-* For most new contributors, there's a lot to learn while making your first
-  pull request. It's OK if it takes you a while; that's normal! You'll be
-  able to work a lot faster as you build experience.
-
-### Working on an issue
-
-To work on an issue, claim it by adding a comment with `@zulipbot claim` to
-the issue thread. [Zulipbot](https://github.com/zulip/zulipbot) is a GitHub
-workflow bot; it will assign you to the issue and label the issue as "in
-progress". Some additional notes:
-
-* You can only claim issues with the
-  [good first issue](https://github.com/zulip/zulip/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22)
-  or
-  [help wanted](https://github.com/zulip/zulip/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22)
-  labels. Zulipbot will give you an error if you try to claim an issue
-  without one of those labels.
-* You're encouraged to ask questions on how to best implement or debug your
-  changes -- the Zulip maintainers are excited to answer questions to help
-  you stay unblocked and working efficiently. You can ask questions on
-  chat.zulip.org, or on the GitHub issue or pull request.
-* We encourage early pull requests for work in progress. Prefix the title of
-  work in progress pull requests with `[WIP]`, and remove the prefix when
-  you think it might be mergeable and want it to be reviewed.
-* After updating a PR, add a comment to the GitHub thread mentioning that it
-  is ready for another review. GitHub only notifies maintainers of the
-  changes when you post a comment, so if you don't, your PR will likely be
-  neglected by accident!
-
-### And beyond
-
-A great place to look for a second issue is to look for issues with the same
-`area:` label as the last issue you resolved. You'll be able to reuse the
-work you did learning how that part of the codebase works. Also, the path to
-becoming a core developer often involves taking ownership of one of these area
-labels.
-
-## What makes a great Zulip contributor?
-
-Zulip has a lot of experience working with new contributors.  In our
-experience, these are the best predictors of success:
-
-* Posting good questions. This generally means explaining your current
-  understanding, saying what you've done or tried so far, and including
-  tracebacks or other error messages if appropriate.
-* Learning and practicing
-  [Git commit discipline](https://zulip.readthedocs.io/en/latest/contributing/version-control.html#commit-discipline).
-* Submitting carefully tested code. This generally means checking your work
-  through a combination of automated tests and manually clicking around the
-  UI trying to find bugs in your work. See
-  [things to look for](https://zulip.readthedocs.io/en/latest/contributing/code-reviewing.html#things-to-look-for)
-  for additional ideas.
-* Posting
-  [screenshots or GIFs](https://zulip.readthedocs.io/en/latest/tutorials/screenshot-and-gif-software.html)
-  for frontend changes.
-* Being responsive to feedback on pull requests. This means incorporating or
-  responding to all suggested changes, and leaving a note if you won't be
-  able to address things within a few days.
-* Being helpful and friendly on chat.zulip.org.
-
-These are also the main criteria we use to select candidates for all
-of our outreach programs.
-
-## Reporting issues
-
-If you find an easily reproducible bug and/or are experienced in reporting
-bugs, feel free to just open an issue on the relevant project on GitHub.
-
-If you have a feature request or are not yet sure what the underlying bug
-is, the best place to post issues is
-[#issues](https://chat.zulip.org/#narrow/stream/9-issues) (or
-[#mobile](https://chat.zulip.org/#narrow/stream/48-mobile) or
-[#desktop](https://chat.zulip.org/#narrow/stream/16-desktop)) on the
-[Zulip community server](https://zulip.readthedocs.io/en/latest/contributing/chat-zulip-org.html).
-This allows us to interactively figure out what is going on, let you know if
-a similar issue has already been opened, and collect any other information
-we need. Choose a 2-4 word topic that describes the issue, explain the issue
-and how to reproduce it if known, your browser/OS if relevant, and a
-[screenshot or screenGIF](https://zulip.readthedocs.io/en/latest/tutorials/screenshot-and-gif-software.html)
-if appropriate.
-
-**Reporting security issues**. Please do not report security issues
-  publicly, including on public streams on chat.zulip.org. You can
-  email security@zulip.com.  We create a CVE for every security
-  issue in our released software.
-
-## User feedback
-
-Nearly every feature we develop starts with a user request. If you are part
-of a group that is either using or considering using Zulip, we would love to
-hear about your experience with the product. If you're not sure what to
-write, here are some questions we're always very curious to know the answer
-to:
-
-* Evaluation: What is the process by which your organization chose or will
-  choose a group chat product?
-* Pros and cons: What are the pros and cons of Zulip for your organization,
-  and the pros and cons of other products you are evaluating?
-* Features: What are the features that are most important for your
-  organization? In the best-case scenario, what would your chat solution do
-  for you?
-* Onboarding: If you remember it, what was your impression during your first
-  few minutes of using Zulip? What did you notice, and how did you feel? Was
-  there anything that stood out to you as confusing, or broken, or great?
-* Organization: What does your organization do? How big is the organization?
-  A link to your organization's website?
-
-## Outreach programs
-
-Zulip participates in [Google Summer of Code
-(GSoC)](https://developers.google.com/open-source/gsoc/) every year.
-In the past, we've also participated in
-[Outreachy](https://www.outreachy.org/), [Google
-Code-In](https://developers.google.com/open-source/gci/), and hosted
-summer interns from Harvard, MIT, and Stanford.
-
-While each third-party program has its own rules and requirements, the
-Zulip community's approaches all of these programs with these ideas in
-mind:
-* We try to make the application process as valuable for the applicant as
-  possible. Expect high-quality code reviews, a supportive community, and
-  publicly viewable patches you can link to from your resume, regardless of
-  whether you are selected.
-* To apply, you'll have to submit at least one pull request to a Zulip
-  repository.  Most students accepted to one of our programs have
-  several merged pull requests (including at least one larger PR) by
-  the time of the application deadline.
-* The main criteria we use is quality of your best contributions, and
-  the bullets listed at
-  [What makes a great Zulip contributor](#what-makes-a-great-zulip-contributor).
-  Because we focus on evaluating your best work, it doesn't hurt your
-  application to makes mistakes in your first few PRs as long as your
-  work improves.
-
-Most of our outreach program participants end up sticking around the
-project long-term, and many have become core team members, maintaining
-important parts of the project. We hope you apply!
-
-### Google Summer of Code
-
-The largest outreach program Zulip participates in is GSoC (14
-students in 2017; 11 in 2018; 17 in 2019; 18 in 2020).  While we don't control how
-many slots Google allocates to Zulip, we hope to mentor a similar
-number of students in future summers.
-
-If you're reading this well before the application deadline and want
-to make your application strong, we recommend getting involved in the
-community and fixing issues in Zulip now. Having good contributions
-and building a reputation for doing good work is the best way to have
-a strong application.  About half of Zulip's GSoC students for Summer
-2017 had made significant contributions to the project by February
-2017, and about half had not.  Our
-[GSoC project ideas page][gsoc-guide] has lots more details on how
-Zulip does GSoC, as well as project ideas (though the project idea
-list is maintained only during the GSoC application period, so if
-you're looking at some other time of year, the project list is likely
-out-of-date).
-
-We also have in some past years run a Zulip Summer of Code (ZSoC)
-program for students who we didn't have enough slots to accept for
-GSoC but were able to find funding for.  Student expectations are the
-same as with GSoC, and it has no separate application process; your
-GSoC application is your ZSoC application.  If we'd like to select you
-for ZSoC, we'll contact you when the GSoC results are announced.

-## Zulip outreach
-
-**Upvoting Zulip**. Upvotes and reviews make a big difference in the public
-perception of projects like Zulip. We've collected a few sites below
-where we know Zulip has been discussed. Doing everything in the following
-list typically takes about 15 minutes.
-* Star us on GitHub. There are four main repositories:
-  [server/web](https://github.com/zulip/zulip),
-  [mobile](https://github.com/zulip/zulip-mobile),
-  [desktop](https://github.com/zulip/zulip-desktop), and
-  [Python API](https://github.com/zulip/python-zulip-api).
-* [Follow us](https://twitter.com/zulip) on Twitter.
-
-For both of the following, you'll need to make an account on the site if you
-don't already have one.
-
-* [Like Zulip](https://alternativeto.net/software/zulip-chat-server/) on
-  AlternativeTo. We recommend upvoting a couple of other products you like
-  as well, both to give back to their community, and since single-upvote
-  accounts are generally given less weight. You can also
-  [upvote Zulip](https://alternativeto.net/software/slack/) on their page
-  for Slack.
-* [Add Zulip to your stack](https://stackshare.io/zulip) on StackShare, star
-  it, and upvote the reasons why people like Zulip that you find most
-  compelling. Again, we recommend adding a few other products that you like
-  as well.
-
-We have a doc with more detailed instructions and a few other sites, if you
-have been using Zulip for a while and want to contribute more.
-
-**Blog posts**. Writing a blog post about your experiences with Zulip, or
-about a technical aspect of Zulip can be a great way to spread the word
-about Zulip.
-
-We also occasionally [publish](https://blog.zulip.org/) long-form
-articles related to Zulip. Our posts typically get tens of thousands
-of views, and we always have good ideas for blog posts that we can
-outline but don't have time to write. If you are an experienced writer
-or copyeditor, send us a portfolio; we'd love to talk!

-      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

-          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

-          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

-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   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
-      this License, without any additional terms or conditions.
-      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.

-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions

-      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.

-    an existing row for the property/(realm, stream, user)/time with subgroup=None, Django would
-    create a duplicate row.
-
-    In the next migration, we'll add a proper constraint to fix this bug, but
-    we need to fix any existing problematic rows before we can add that constraint.
-
-    We fix this in an appropriate fashion for each type of CountStat object; mainly

+#### Dependencies
+
+The [Zulip API](https://zulip.com/api) Python bindings require the
+following Python libraries:
+
+* simplejson
+* requests (version >= 0.12.1)
+
+
+#### Installing
+
+This package uses distutils, so you can just run:
+
+    python setup.py install
+
+#### Using the API
+
+For now, the only fully supported API operation is sending a message.
+The other API queries work, but are under active development, so
+please make sure we know you're using them so that we can notify you
+as we make any changes to them.
+
+The easiest way to use these API bindings is to base your tools off
+of the example tools under examples/ in this distribution.
+
+If you place your API key in the config file `~/.zuliprc` the Python
+API bindings will automatically read it in. The format of the config
+file is as follows:
+
+    [api]
+    key=<api key from the web interface>
+    email=<your email address>
+
+If you are using Zulip Enterprise, you should also add
+
+    site=<your Zulip Enterprise server's URI>
+
+Alternatively, you may explicitly use "--user" and "--api-key" in our
+examples, which is especially useful if you are running several bots
+which share a home directory.  There is also a "--site" option for
+setting the Zulip Enterprise server on the command line.
+
+You can obtain your Zulip API key, create bots, and manage bots all
+from your Zulip [settings page](https://zulip.com/#settings).
+
+A typical simple bot sending API messages will look as follows:
+
+At the top of the file:
+
+    # Make sure the Zulip API distribution's root directory is in sys.path, then:
+    import zulip
+    zulip_client = zulip.Client(email="your-bot@example.com", client="MyTestClient/0.1")
+
+When you want to send a message:
+
+    message = {
+      "type": "stream",
+      "to": ["support"],
+      "subject": "your subject",
+      "content": "your content",
+    }
+    zulip_client.send_message(message)
+
+Additional examples:
+
+    client.send_message({'type': 'stream', 'content': 'Zulip rules!',
+                         'subject': 'feedback', 'to': ['support']})
+    client.send_message({'type': 'private', 'content': 'Zulip rules!',
+                         'to': ['user1@example.com', 'user2@example.com']})
+
+send_message() returns a dict guaranteed to contain the following
+keys: msg, result.  For successful calls, result will be "success" and
+msg will be the empty string.  On error, result will be "error" and
+msg will describe what went wrong.
+
+#### Logging
+The Zulip API comes with a ZulipStream class which can be used with the
+logging module:
+
+```
+import zulip
+import logging
+stream = zulip.ZulipStream(type="stream", to=["support"], subject="your subject")
+logger = logging.getLogger("your_logger")
+logger.addHandler(logging.StreamHandler(stream))
+logger.setLevel(logging.DEBUG)
+logger.info("This is an INFO test.")
+logger.debug("This is a DEBUG test.")
+logger.warn("This is a WARN test.")
+logger.error("This is a ERROR test.")
+```
+
+#### Sending messages
+
+You can use the included `zulip-send` script to send messages via the
+API directly from existing scripts.
+
+    zulip-send hamlet@example.com cordelia@example.com -m \
+        "Conscience doth make cowards of us all."
+
+Alternatively, if you don't want to use your ~/.zuliprc file:
+
+    zulip-send --user shakespeare-bot@example.com \
+        --api-key a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5 \
+        hamlet@example.com cordelia@example.com -m \
+        "Conscience doth make cowards of us all."

+This bot requires the feedparser module.
+
+To use this script:
+
+1. Create an RSS feed file containing 1 feed URL per line (default feed
+   file location: ~/.cache/zulip-rss/rss-feeds)
+2. Subscribe to the stream that will receive RSS updates (default stream: rss)
+3. create a ~/.zuliprc as described on https://zulip.com/api#api_keys
+4. Test the script by running it manually, like this:
+
+/usr/local/share/zulip/integrations/rss/rss-bot
+
+You can customize the location on the feed file and recipient stream, e.g.:
+
+/usr/local/share/zulip/integrations/rss/rss-bot --feed-file=/path/to/my-feeds --stream=my-rss-stream
+
+4. Configure a crontab entry for this script. A sample crontab entry for
+processing feeds stored in the default location and sending to the default
+stream every 5 minutes is:
