"""
A MkDocs File object.
It represents how the contents of one file should be populated in the destination site.
A file always has its `abs_dest_path` (obtained by joining `dest_dir` and `dest_path`),
where the `dest_dir` is understood to be the *site* directory.
`content_bytes`/`content_string` (new in MkDocs 1.6) can always be used to obtain the file's
content. But it may be backed by one of the two sources:
* A physical source file at `abs_src_path` (by default obtained by joining `src_dir` and
`src_uri`). `src_dir` is understood to be the *docs* directory.
Then `content_bytes`/`content_string` will read the file at `abs_src_path`.
`src_dir` *should* be populated for real files and should be `None` for generated files.
* Since MkDocs 1.6 a file may alternatively be stored in memory - `content_string`/`content_bytes`.
Then `src_dir` and `abs_src_path` will remain `None`. `content_bytes`/`content_string` need
to be written to, or populated through the `content` argument in the constructor.
But `src_uri` is still populated for such files as well! The virtual file pretends as if it
originated from that path in the `docs` directory, and other values are derived.
For static files the file is just copied to the destination, and `dest_uri` equals `src_uri`.
For Markdown files (determined by the file extension in `src_uri`) the destination content
will be the rendered content, and `dest_uri` will have the `.html` extension and some
additional transformations to the path, based on `use_directory_urls`.
