# cygwin/mknetrel - LilyPond mknetrel overrides

# This script should be used to package LilyPond for Cygwin.
# It can be used to build LilyPond on Cygwin, but also on GNU/Linux.
#
# See http://lilypond.org/web/devel/packaging.html for more information,
# report bugs to bug-lilypond@gnu.org.
#
# To build the package, do:
cat >/dev/null <<EOC
