I'm writing a Ruby gem that will need an initial configuration (username, etc...). Where should I save this config file for it to be:
- portable (various Linux distros / OS X)
- not requiring
sudo - not inside the gem directory as the config should persist between gem versions
Thanks!
EDIT: As suggested by @NeilSlater in the comments, I want to precise that the gem will install some CLI tools (some will be run through a GUI) and will not be used by developers, hence the need to make it as easy as possible to configure.
