0.1     Imported files from old repository. Created README, HISTORY,
	Benchmark.
0.2	Major refactor; the alignment module is now based on classes.
	Reorganized help message and added new output formats
	bpf+trn and trn.
0.3	Fixed a bug that led to temporary directories not being
	unique, turned --verbose and --clean into flags
0.4	Added --maxlength parameter which sets a limit on subtitle
	length.
0.5	Shorter and specific ERROR messages for missing input files or missing
        tiers ORT/MAU in bpf input file;
        tiers TRO/TRN are deleted from input bpf before processing
0.6     Added UTF-8 character '…' to the list of punctuation chars
0.7     Changed transcription tokenization strategy:
	-Splitting punctuation and non-punctuation (e.g., test.test -> test. test)
	-Not splitting on punctuation inside tags
        (punctuations are: !?:.… but NOT ,;)
0.8	If no transcription is provided, use TRO tier in BPF.
0.9	subtitle -> subtitle.py; new wrapper subtitle that aggregates non-linked ('-1')
        elements in TRO tier to the previous TRO token; that way TRO tokens like
        '!\n' are appended to the previous word and thus the output of 
        annotation formats like TextGrid contain the full text.
