Re: [Configobj-develop] some enhancements

[Jack K. <kj...@gm...>]

Hi Nicola and all,

thanks for your time in going through my proposed features.
Although all of them were added because I felt convenient to have them while
writing my own configuration
files, I agree that not every one will like or need the same features. I
shared my work with the hope that someone might find it useful; if it's
integrated back to the project, that's great; if it's not accepted, I'm
already grateful to have had the chance on improving the project and sharing
and expressing my contributions!

Thank you all, and happy new year!
Jack
