Usage samples

[ricemouse]

I have used your tools in my projects. Thus I want to contribute some useful examples to help users understand how to use this tool.

The scenarios includes transfer json to properties, docker-compose.yml, etc

Also made some minor changes to refine the code structure.

Thanks for your pull request!

I love the idea with the samples.

I can also see what you are trying to do with the print statements, but I would not want them to be printed always.

I have two requests:

• make the print statements dependent on a command line flag ( -v for verbose comes to mind)
• remove the pprint import as you are not using it

Thanks again for your contribution and I'm happy meta-compose was of help for you!
