I am developing an API in Unix environment for virtual machines. Most of the modules are developed in python. I have few questions on this.

I have the file extension as abc.py. I would like to make this as a command. For example , virtman dominfo [vmid] should be the command syntax. Now I have to give ./virtman.py dominfo [vmid] to achieve this. And I have first line as #!/usr/bin/python in the python file. So how can make this as a command?

I read a lot of articles but I didn't get the clear picture,so any hints/suggestions would be helpful.
