Converts OpenSong song files to OnSong format

Usage

Pretty easy to use - just make sure that Ruby is installed, then run this:

ruby opensong_to_onsong.rb ./path_to_opensong_file.xml > ./export_filename.txt

It just outputs straight to STDIO.

# Express app templating for Rails
# ------------------------------------
# USAGE:
# 1. Add gems to `gem_dependencies`
# 2. Methods listed in SCRIPTS will be run after bundling, so make sure they each have a declaration
# 3. run: `rails new app_name --builder=path/to/builder.rb` (URI's work here too)
