 ## Scope
 This gem is aimed to recursively collect the `runtime dependencies` footprint of the specified gem.  
 The output of the library mimics the `tree` shell utility, highlighting the nested dependencies via ASCII characters.

 #### bundle viz
 The *bundle viz* command relies on the Gemfile and the [graphviz](http://www.graphviz.org/) library to generate a visual representation of the gem inter-dependencies.  
 While it is great to visualize inter-dependencies, i have hard times figuring out gem's  runtime footprint.
 
 ## Warning
-Consider only the gems installed on your system are scanned by the library.

 This library invokes the `Gem::Commands::DependencyCommand` class recursively to collect all the levels of dependency.  
 Both runtime and development dependencies are counted (identical dependencies are counted once).  
 Just the runtime dependencies tree is printed to screen:

+### Version
+By default this library scans for the first version `>= 0`.  
+In case you have multiple versions of a gem installed, just specify the version you need to cut as the second argument:
