# test basic Machine interface (MI) operations

#

# Verify that, using the MI, we can load a program and do

# other basic things that are used by all test files through  mi_gdb_exit,

# mi_gdb_start, mi_delete_breakpoints, mi_gdb_reinitialize_dir and

# mi_gdb_load, so we can safely use those.

#

# The goal is not to test gdb functionality, which is done by other tests,

# but the command syntax and correct output response to MI operations.
