- I used mknetrel. My last cygwin/mknetrel is attached. (No patch yet, 
sorry.)
- I also attach a shell script that describes quite well what is missing 
from mknetrel, and what problems there were. (For example in cygwin 
lilypond.info must not be in a lilypond subdirectory, there should not 
be a postremove script - because bash may be uninstalled before the 
postremove script - etc.)
