# With this class registered (and assuming the executable that calls `Cl` is

#
# $ bin/run git:pull master # instantiates Git::Pull, and passes ["master"] as args
# $ bin/run git pull master # does the same

Cl.new('run').run(%w(git:pull master))
# Output:
#
#   {:cmd=>:"git:pull", :args=>["master"]}

Cl.new('run').run(%w(git pull master))
# Output:
#
#   {:cmd=>:"git:pull", :args=>["master"]}
