Arturo actually supports these following sites:

• http://www.italiasubs.net
• http://www.subsfactory.it
• http://www.tvsubtitles.net

These sites are great because subtitles are divided in pages with specific tv series name and season.

If you want to create a new plugin for www.foosubtitles.cz, you have to:

1. go to Arturo plugins folder
2. create a folder named cz
3. create a file named foosubtitles.py (the easiest way is to copy and paste an old plugin and rename it)
4. modify it

Plugins are just Python files that must adhere to this specification:

class Scraper(object):    
	#This class has to be called Scraper, that's it!	

    def __init__(self,opener,tvseries_config):       
	#This constructor initialize the opener and, as it is called just one time, can be used for site authentication 

    def get_subtitles_file_url_list(self,tvseries_config):
	#This method does the dirty job!
 	#Starting from tv series url, using regular expression, it has to return a list of url like this:
	#['http://www.foosubtitles.cz/download/sub_episodes1.zip','http://www.foosubtitles.cz/download/sub_episodes2.zip',..]

Remember, plugins are not forever! If subtitles repositories change its layout, plugin probably will miserably start to fail.

Have fun!
