It seems to be equipped to run as a program:

lgc$ wget 
http://lilykde.googlecode.com/svn/trunk/frescobaldi/python/ly/indent.py
lgc$
lgc$ python -V
Python 2.6.5
lgc$
lgc$ python indent.py -t 2 Heidenroeslein.ly
Traceback (most recent call last):
  File "indent.py", line 252, in <module>
    startscheme=options.scheme
  File "indent.py", line 107, in indent
    usetabs = '\t' in space or '\n\t' in text
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 48: 
ordinal not in range(128)
lgc$

I don't have experience with python Unicode support. Is 2.6.5 new enough for 
this to work?

Exactly. My intended application is to use it as part of a git
collaboration workflow that Urs, Janek, Susan(?) and I are working on.

Cheers,
