# This script changes the bootstrap code for all Phusion Passenger commands,
# as well as the Nginx module config script, so that they work no
# matter which Ruby interpreter is currently in $PATH, and no matter how
# Phusion Passenger is packaged.
# 
# The bootstrap code must not add ruby_libdir to $LOAD_PATH. The active Ruby
# can be *any* Ruby interpreter, maybe not even MRI. ruby_libdir belongs to
# a Ruby interpreter installed by the distribution, and the files in it may
# may be incompatible with the active Ruby.
