    """ Files will be uploaded to MEDIA_ROOT/blog/<year of publishing>/<blog

    title>

    The blog title is determined by the text before the first period (".") in

    the filename. So if the file has the name "Trains are bæ.en.md", the file

    will be stored in "blog/<this year>/Trains are bæ". Name your files

    properly!

    It should also be noted that all files are stored in the same folder if they

    belong to the same blogpost, regardless of language. The titles that are

    displayed to the user however, should be the titles of the files themselves,

    which should be in the native language. So if a blog post is titled

    "Universities of Belgium", its Dutch counterpart should be titled

    "Universiteiten van België", so the correct title can be derived from the

    filename.

    Recommended way to name the uploaded file: "<name of blog post in language

    it's written>.md". This removes the maximum amount of redundancy (e.g. the

    language of the file can be derived from the title, no ".fr.md" or something

    like that necessary), and can directly be used for the end user (the title

    is what should be displayed).
