  # NAME
  
  Perl6::Ecosystem - Obtains information from Perl6 modules in the ecosystem
  
  # SYNOPSIS
  
  ```
  use Perl::Ecosystem;
  my $eco = Perl6::Ecosystem.new;
  
  say $eco.modules;
  say $eco.depended;
  say $eco.depends-on;
  
  ```
  
  # DESCRIPTION
  
  A tool to analyze the Perl 6 ecosystem by downloading all modules and finding out how they depend on each other.
  
  # METHODS
  
  ## method new( )
  
  Creates the object, downloading and filling it with information. Error output goes to `/tmp/perl6-eco-err.txt`
  
  ## method modules
  
  Returns a `hash` with module names, dependencies and URLs.
  
  ## method depended
  
  Returns a `hash` with module names and the number of other modules it depends on.
  
  ## method depends-on
  
  Returns a `hash` with module names and its dependencies.
  
  ## method river-scores --> Hash
  
  Computes the "river-score" by looking at all dependency chains and giving a score according to the position. That is, if there's this dependenci chain
  
  ```
  Foo → Bar → Baz
  
  ```
  
  Foo will have a 0 score for appearing in the first position, up to Baz which will have score equal to 2. The total score of every module is computed by adding all scores.
