I do not understand why the image-tools in the three sub-command split into three software, I think these three commands should be combined into a tool, after all, they belong to image-tools, I think the merger will Easy to understand and application, if I was a user, I would think that the use of a software implementation of the three commands than the use of three software to implement a command to be more convenient.
I currently have a plan to merge, don't know how you think .
