Content-Subdirectory:
If you intend to use the IMaGen-application (Internet-Magazine-Generator) then you must
specify a subdirectory (beneath the 'Local Project Dir'), where the 'content' of your
magazine shall be stored. If not existent, it will be created automatically.

If you write an article within IMaGen, the article-file is stored in a subdirectory under
the content-subdirectory, using a path built from the rubrics in which the article is
composed.

Example:
Let your local project directory by 'c:\data\webmag1\'; you write an article as part of the 'Sports'-chapter, in the 'Football'-section and, further
detailed, in the 'Young Talents'-subsection. Then your article will be stored in
'c:\data\webmag1\Sports\Football\Young Talents\<article-name>.art'
The article-name is built from its time-stamp, with the file extension of 'art'.

Keep in mind, that - different from usual behaviour in phpGUI - the uploaded article
will NOT replicate its local path on the server, instead the article will be stored in a
MySQL-database (table-name 'Artikel').
