## Installation
Add this line to your application's Gemfile:
```ruby
gem 'license-compatibility'
```
And then execute:
$ bundle
Or install it yourself as:
$ gem install license-compatibility
## Usage
On the command-line:
`license-compatibility [-h] [-v] [-l] [-r file] [args]`
Arguments are a list of licenses or a list of package:license couples.
Examples:
```
license-compatibility MIT GPL-3.0 Unlicense
license-compatibility my_package:ISC other_pkg:BSD-2-Clause
```
Mixing the two formats is not allowed.
Additional args after a --read option are accepted.
Options:
- **-l, --list**: Print the list of supported licenses.
- **-r, --read FILE**: Read arguments from file.
- **-v, --version**: Show the program version.
- **-h, --help**: Print help message.
In your code:
```ruby
License::Compatibility.forward_compatibility('MIT', 'GPL-3.0') #=> true
```
## Development
After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
