"""
Plain class for executing e-uae with specified parameters. This is useful for
running things from floppies. It creates new .uaerc file with substituted all
templates with proper values and run. Floppies usually are unpacked or only
gzipped (which is supported by emulator itself) so there is no need to copy
them to temporary place.
Unlike other modules, there is no path changing during running e-uae.
