    # rnsubs: no such directory: 'Subs'
	#    
	#    rnsubs is means for a directory structure like:
	#    - file1
	#    - file2
	#
	#    - Subs/file1/2_English.srt
	#    - Subs/file1/3_English.srt
	#
	#    - Subs/file2/2_English.srt
	#    - Subs/file2/3_English.srt
	#    - Subs/file2/4_English.srt
	#    - Subs/file2/5_English.srt
	#    
	#    When run in the main directory, it will move the *_English.srt files under Subs
	#	 to the top level like so:
	#
	#    	- file1.srt
	#    	- file1.SDH.srt
	#
	#    	- file2.srt
	#    	- file2.SDH.srt
	#    	- file2.FOREIGN.srt
	#    	- file2.4.srt
