@moduledoc """
A `Plug` to automatically set the `content_type` of every `Plug.Upload`.
One of the required option of `pool`, `server` or `once` must be set.
Additional options:
* `fix_extension`, default true: rewrite the user provided `filename` with a valid extension for the detected content type
* `append_extension`, default false: append the valid extension to the previous filename, without removing the user provided extension
To use a gen_magic pool:
```
plug Majic.Plug, pool: MyApp.MajicPool
```
To use a single gen_magic server:
```
plug Majic.Plug, server: MyApp.MajicServer
```
To start a gen_magic process at each file (not recommended):
```
plug Majic.Plug, once: true
```
