Provides a very simple save-file functionality. I liked the name 'save_file()' a lot, and I found that I was needing such a functionality in many of my projects, so I made a tiny gem that would do exactly this. This project has no external dependencies. Version 1.0.3 made it more clear when to use save_file() and when to use append_into_file().
Gemfile gem 'save_file', '~> 1.0.18'
install gem install save_file
