You know that Frescobaldi can convert absolute to relative and vice

As can the ly standalone (derived from F~ possibly).
Sorry I don't understand.
ly, packaged as python3-ly in Debian, has a number of commands hived
off (I assume) from Fresco including: re-indent, reformat, translate
the language, transpose, abs2rel, rel2abs, simplify-accidentals, etc.
Originally ly was the module *inside* Frescobaldi handling all the stuff
relating to the LilyPond input code. This includes functions like code
formatting, musical changes, trying to keep track of where we are in the
music etc.
At some point Wilbert decided to a) remove any dependencies on Qt (the
application development framework used in Frescobaldi) from that code,
b) factor it out into an external module and c) make a standalone script
wrapping some of its functionality.
So a number of functions are available through that 'ly' command line
script, and it's also possible to 'import ly' in Python programs. At
some later point I also added an HTTP server wrapper so you could
actually use 'ly' in a web application to submit your LilyPond code for
processing in a website.
When Frescobaldi decided to completely move to Python 3, dropping all
Python 2 compatibility efforts this was deliberately *not* applied to
python-ly, so that is a plain Python 2/3 library that can be used from
both Python versions, without any PyQt dependencies.
Just for some clarification.
