"""
A MkDocs File object.
Points to the source and destination locations of a file.
The `path` argument must be a path that exists relative to `src_dir`.
The `src_dir` and `dest_dir` must be absolute paths on the local file system.
The `use_directory_urls` argument controls how destination paths are generated. If `False`, a Markdown file is
mapped to an HTML file of the same name (the file extension is changed to `.html`). If True, a Markdown file is
mapped to an HTML index file (`index.html`) nested in a directory using the "name" of the file in `path`. The
`use_directory_urls` argument has no effect on non-Markdown files.
File objects have the following properties, which are Unicode strings:
