+This program returns the quota of 1st level sub directories in a directory
+using the ``du`` command (available on all \*nix platforms).
+If no start directory is given all directories in the current one will be
+Sometimes it is required to get the quota of a defined subset of directories.
+It is possible to give folder names as arguments::
+ $ qcheck directory-1 directory-2
+This method only makes sense for a couple of directories. Longer folder lists
+can be passed as a text file containing one folder per line. Pass the filename
+of the text file to the program using the ``-t`` argument::
+ $ qcheck -t folder_set.txt
+By default the result is written to the standard output, size is denoted in
+Each directory-quota will be presented in one line::
+The output can also converted to a human readable form with the ``-r``
+If the file output is enabled with the argument ``-f FILENAME`` the output will
+be written to a csv-file. The file will be created if it does not exist.
+If the *file* already exists, the new content will be added as a new column to
+the document. The name of the column contains the date like ``YY-MM``:
+.. csv-table:: Example CSV output
+If the *column* already exists quotachecker will return a note that you have to
+set the ``-o`` parameter if you want to overwrite the column and exit. If the
+``-o`` argument is set quotachecker will overwrite the column if it exists.
+If the installed Python version is at least 2.7 you have all what you need and
+there is nothing to install.
+If the installed Python version is 2.6 or less you need to install `argparse
+<http://pypi.python.org/pypi/argparse>`_ wich has already been done if you
+installed the quotachecker with pip.
+If something doesn't work as described please first run the tests::
+and send me the output if it fails.
