+"""
+Quality assessment configuration file for the CelebA database to be used
+with quality assessment script.
+
+Note: this config checks the quality of the preprocessed(!) data. Here the
+preprocessed data is sored in ``.hdf5`` files, as a frame container with
+one frame. Frame contains a BW image of the facial regions of the size
+128x128 pixels.
+
+The config file MUST contain at least the following functions:
+
+``load_datafile(file_name)`` - returns the ``data`` given ``file_name``, and
+
+``assess_quality(data, **assess_quality_kwargs)`` - returns ``True`` for good
+quality ``data``, and ``False`` for low quality data, and
+
+``assess_quality_kwargs`` - a dictionary with kwargs for ``assess_quality()``
+function.
