 def _GenerateLibraryPath(self, tvFile, libraryDir):
 """ Creates a full path for TV file in TV library. This initially attempts to directly match a show directory in the database, if this fails it searches the library directory for the best match. The user can then select an existing match or can propose a new directory to use as the show root directory. The season directory is also generated and added to the show and library directories. This is then used by the tvFile GenerateNewFilePath method to create a new path for the file. Parameters tvFile : tvfile.TVFile Contains show and file info. libraryDir : string Root path of TV library directory. Returns tvfile.TVFile This is an updated version of the input object. """
