Can you please tell me .. how to use ASCMD command line utility ?

I want to prepare deployment package in terms of batch file to execute .xmla files to create cubes and then prepare jobs to process those cubes.

I am familiar with SQLCMD, but i have no idea about ASCMD ... is it a third party tool that we need to install first ?

Please let me know if u know how to deploy cube using command prompt.

Thanks in advance.
