README
Licensir 
An Elixir mix task that list the license(s) of all installed packages in your project.
Installation
The package can be installed by adding licensir to your list of dependencies in mix.exs:
def deps do
[
{:licensir, "~> 0.6", only: :dev, runtime: false}
]
end
This mix task in most cases only needs to be run on a development machine and independent from the runtime applications, hence the only: dev, runtime: false options.
Install locally
If you do not wish to include this tool as part of your dependencies, you may also install it locally by running:
$ mix archive.install hex licensir 0.6.2
Now you can access this tool from any path on your local machine that has access to mix.
Usage
Run mix licenses to get the list of packages and their licenses:
$ mix licenses

Run mix licenses --csv to output in csv format:
Package,Version,License
certifi,,BSD
earmark,1.3.2,Apache 2.0

excoveralls,,"Unsure (found: MIT, Unrecognized license file content)"

Flags
--top-level-only- Only fetch license information from top level dependencies (e.g. packages that are directly listed in your application'smix.exs). Excludes transitive dependencies.
Usage as a library
You may call the function Licensir.Scanner.scan() from your Elixir application to get a list of license data per dependency.
iex> Licensir.Scanner.scan([])

%Licensir.License{
app: :jason,
dep: %Mix.Dep{
