# render_groupSimilarFiles.sh -- This function provides
# post-rendition action to group files inside directories named as
# their file extensions.  For example: if the current file is a .png
# file, it is moved inside a Png/ directory; if the current file is a
# .jpg file, it is stored inside a Jpg/ directory, and so on.
#
# For this function to work correctly, you need to specify which file
# type you want to group. This is done in the post-rendition ACTIONS
# array inside the appropriate `render.conf.sh' pre-configuration
# script. This function cannot be used as last-rendition action.
