 """Blast list of sequences. seqs: either file name or list of sequence objects or list of strings or single multiline string containing sequences. WARNING: DECISION RULES FOR INPUT HANDLING HAVE CHANGED. Decision rules for data are as follows. If it's s list, treat as lines, unless add_seq_names is true (in which case treat as list of seqs). If it's a string, test whether it has newlines. If it doesn't have newlines, assume it's a filename. If it does have newlines, it can't be a filename, so assume it's a multiline string containing sequences. If you want to skip the detection and force a specific type of input handler, use input_handler='your_favorite_handler'. add_seq_names: boolean. if True, sequence names are inserted in the list of sequences. if False, it assumes seqs is a list of lines of some proper format that the program can handle """
