+
+asyncio-compatible timeout context manager.
+
+
+Usage example
+-------------
+
+
+The context manager is useful in cases when you want to apply timeout
+logic around block of code or in cases when ``asyncio.wait_for()`` is
+not suitable. Also it's much faster than ``asyncio.wait_for()``
+because ``timeout`` doesn't create a new task.
+
+The ``timeout(delay, *, loop=None)`` call returns a context manager
+that cancels a block on *timeout* expiring::
+
+   from async_timeout import timeout
+   async with timeout(1.5):
+       await inner()
+
+1. If ``inner()`` is executed faster than in ``1.5`` seconds nothing
+   happens.
+2. Otherwise ``inner()`` is cancelled internally by sending
+   ``asyncio.CancelledError`` into but ``asyncio.TimeoutError`` is
+   raised outside of context manager scope.
+
+*timeout* parameter could be ``None`` for skipping timeout functionality.
+
+
+Alternatively, ``timeout_at(when)`` can be used for scheduling
+at the absolute time::
+
+   loop = asyncio.get_event_loop()
+   now = loop.time()
+
+   async with timeout_at(now + 1.5):
+       await inner()
+
+
+Please note: it is not POSIX time but a time with
+undefined starting base, e.g. the time of the system power on.
+
+
+Context manager has ``.expired`` property for check if timeout happens
+exactly in context manager::
+
+   async with timeout(1.5) as cm:
+       await inner()
+   print(cm.expired)
+
+The property is ``True`` if ``inner()`` execution is cancelled by
+timeout context manager.
+
+If ``inner()`` call explicitly raises ``TimeoutError`` ``cm.expired``
+is ``False``.
+
+The scheduled deadline time is available as ``.deadline`` property::
+
+   async with timeout(1.5) as cm:
+       cm.deadline
+
+Not finished yet timeout can be rescheduled by ``shift_by()``
+or ``shift_to()`` methods::
+
+   async with timeout(1.5) as cm:
+       cm.shift(1)  # add another second on waiting
+       cm.update(loop.time() + 5)  # reschedule to now+5 seconds
+
+Rescheduling is forbidden if the timeout is expired or after exit from ``async with``
+code block.
+
+
+Installation
+------------
+
+::
+
+   $ pip install async-timeout
+
+The library is Python 3 only!

+## ⚡ Performance
+
+This package offer better performance than its counterpart Chardet. Here are some numbers.
+
+| Package                                       | Accuracy | Mean per file (ms) | File per sec (est) |
+|-----------------------------------------------|:--------:|:------------------:|:------------------:|
+| [chardet](https://github.com/chardet/chardet) |   86 %   |       200 ms       |     5 file/sec     |
+| charset-normalizer                            | **98 %** |     **10 ms**      |    100 file/sec    |
+
+| Package                                       | 99th percentile | 95th percentile | 50th percentile |
+|-----------------------------------------------|:---------------:|:---------------:|:---------------:|
+| [chardet](https://github.com/chardet/chardet) |     1200 ms     |     287 ms      |      23 ms      |
+| charset-normalizer                            |     100 ms      |      50 ms      |      5 ms       |
+
+Chardet's performance on larger file (1MB+) are very poor. Expect huge difference on large payload.
+
+> Stats are generated using 400+ files using default parameters. More details on used files, see GHA workflows.
+> And yes, these results might change at any time. The dataset can be updated to include more files.
+> The actual delays heavily depends on your CPU capabilities. The factors should remain the same.
+> Keep in mind that the stats are generous and that Chardet accuracy vs our is measured using Chardet initial capability
+> (eg. Supported Encoding) Challenge-them if you want.
+
+## ✨ Installation
+
+Using pip:
+
+```sh
+pip install charset-normalizer -U
+```
+
+## 🚀 Basic Usage
+
+### CLI
+This package comes with a CLI.
+
+```
+usage: normalizer [-h] [-v] [-a] [-n] [-m] [-r] [-f] [-t THRESHOLD]
+                  file [file ...]
+
+The Real First Universal Charset Detector. Discover originating encoding used
+on text file. Normalize text to unicode.
+
+positional arguments:
+  files                 File(s) to be analysed
+
+optional arguments:
+  -h, --help            show this help message and exit
+  -v, --verbose         Display complementary information about file if any.
+                        Stdout will contain logs about the detection process.
+  -a, --with-alternative
+                        Output complementary possibilities if any. Top-level
+                        JSON WILL be a list.
+  -n, --normalize       Permit to normalize input file. If not set, program
+                        does not write anything.
+  -m, --minimal         Only output the charset detected to STDOUT. Disabling
+                        JSON output.
+  -r, --replace         Replace file when trying to normalize it instead of
+                        creating a new one.
+  -f, --force           Replace file without asking if you are sure, use this
+                        flag with caution.
+  -t THRESHOLD, --threshold THRESHOLD
+                        Define a custom maximum amount of chaos allowed in
+                        decoded content. 0. <= chaos <= 1.
+  --version             Show version information and exit.
+```
+
+```bash
+normalizer ./data/sample.1.fr.srt
+```
+
+or
+
+```bash
+python -m charset_normalizer ./data/sample.1.fr.srt
+```
+
+🎉 Since version 1.4.0 the CLI produce easily usable stdout result in JSON format.

+### Python
+*Just print out normalized text*
+```python
+from charset_normalizer import from_path
+
+results = from_path('./my_subtitle.srt')
+
+print(str(results.best()))
+```
+
+*Upgrade your code without effort*
+```python
+from charset_normalizer import detect
+```
+
+The above code will behave the same as **chardet**. We ensure that we offer the best (reasonable) BC result possible.
+
+See the docs for advanced usage : [readthedocs.io](https://charset-normalizer.readthedocs.io/en/latest/)
+
+## 😇 Why
+
+When I started using Chardet, I noticed that it was not suited to my expectations, and I wanted to propose a
+reliable alternative using a completely different method. Also! I never back down on a good challenge!
+
+I **don't care** about the **originating charset** encoding, because **two different tables** can
+produce **two identical rendered string.**
+What I want is to get readable text, the best I can. 
+
+In a way, **I'm brute forcing text decoding.** How cool is that ? 😎
+
+Don't confuse package **ftfy** with charset-normalizer or chardet. ftfy goal is to repair unicode string whereas charset-normalizer to convert raw file in unknown encoding to unicode.
+
+## 🍰 How
+
+  - Discard all charset encoding table that could not fit the binary content.
+  - Measure noise, or the mess once opened (by chunks) with a corresponding charset encoding.
+  - Extract matches with the lowest mess detected.
+  - Additionally, we measure coherence / probe for a language.
+
+**Wait a minute**, what is noise/mess and coherence according to **YOU ?**
+
+*Noise :* I opened hundred of text files, **written by humans**, with the wrong encoding table. **I observed**, then
+**I established** some ground rules about **what is obvious** when **it seems like** a mess.
+ I know that my interpretation of what is noise is probably incomplete, feel free to contribute in order to
+ improve or rewrite it.
+
+*Coherence :* For each language there is on earth, we have computed ranked letter appearance occurrences (the best we can). So I thought
+that intel is worth something here. So I use those records against decoded text to check if I can detect intelligent design.
+
+## ⚡ Known limitations
+
+  - Language detection is unreliable when text contains two or more languages sharing identical letters. (eg. HTML (english tags) + Turkish content (Sharing Latin characters))
+  - Every charset detector heavily depends on sufficient content. In common cases, do not bother run detection on very tiny content.
+
+## ⚠️ About Python EOLs
+
+**If you are running:**
+
+- Python >=2.7,<3.5: Unsupported
+- Python 3.5: charset-normalizer < 2.1
+- Python 3.6: charset-normalizer < 3.1
+- Python 3.7: charset-normalizer < 4.0
