This method implements the command line compiler. See the USAGE_STRING
constant for a description. It may make sense to move the command-line
handling to a separate package (ie. make one xsltc.cmdline.Compiler
class that contains this _main() method and one xsltc.cmdline.Transform
class that contains the DefaultRun stuff).
