[ usage ]

at first , create a project

[root@f18 hattori]# multimech-newproject my_project

directory “my_project” will be created at your current working directory.

[root@f18 hattori]# ls my_project/ config.cfg  test_scripts

config.cfg : load , user definition file

test_scripts : python scripts for testing
