Changed PHYSFS_file to PHYSFS_File to match rest of API's naming convention. This won't break binary compat (function signatures are extern "C" so name mangling doesn't apply), and I've placed a typedef for the old name to support legacy source code.

#!/usr/local/bin/ruby

if __FILE__ == $0
  require 'slimb/installer'
  files = ["physfs.rb", "physfs_so.so"]
  installer = Slimb::Installer.new.run files, ARGV
end
