# Running JRuby on OS X requires options passed at the start. To pass those
# options and avoid double JVM startup, we want 'shoes' to be a bash script on
# Unix systems, but Rubygems only supports installing Ruby to the bin.

# We work around this by installing our script as shoes-stub, then acting like
# a "native extension" via this Rakefile, we manually generate the right script
# (a copy of shoes-stub) in the Gem.bindir.

# Because we don't actually declare shoes as an executable, we also have to
# copy our shoes.bat into place as well on Windows systems.

# We also provide a Rubygems plugin to clean up our manual file on uninstall.
# Post-install hooks didn't seem to work, though, hence the extension trick.
