Yes, there is a command line available triggered by the RevoCMD.EXE, but this feature is available only in the Pro version. The free version (the one that I have installed) doesn't contain such file. You will have to buy the application in order to take advantage of the cmd line support.

According to the official website, you can trigger these following commands:
RevoCmd /m "program name" [/i] [/u] [/p]
/m - Match program name using wildcard characters - * and ?
The asterisk (*) wildcard represents any collection of characters
The question mark (?) wildcard represents any single character
