Re: New ‘guix graph’ command

[Mathieu Lirzin]

Nice job, It is really convenient to have such utility.

Does it sound feasible to produce different edge colors depending of the type
of inputs?

Not really important, but IMO it would be clearer to define bag-emerged
in terms of what bag is doing with something like this.

‘bag’                                                           
     This is the package DAG, _including_ implicit inputs.              
                                                                        
‘bag-emerged’                                                                   
     Similar to ‘bag’, but this time without all the bootstrap
     dependencies.

     For instance, the following command:                               
                                                                        
          guix graph --type=bag-emerged coreutils | dot -Tpdf > dag.pdf 
                                                                        
     [...]
