# lilytex-wins.py -- LilyPond command for .lytex on Windows
# By Joshua Leung (address@hidden), based on lily-wins.py
# useful for LilyPond 2.4.2 - Recent lower versions may also work.

# To make it work with a windows right-click, add this to file-type 
associations
# for the .lytex extension. Change the cygwin directory to the correct place 
for
# your system. Also, place this in the right place.
#	C:\cygwin\bin\bash.exe --login -c '/bin/lilytex-wins "%1"'

# Coded 12 April 2005.
# 	12/04/05 	- It works with files in a user's home dir. Not sure about 
other places.
#			- EDIT: it falls down when path has spaces. why, I don't know. how to 
fix, I don't know.
#			- after a short break, it works!
