# wallaby show-feature F
Console Connection Established...
F
  name:  "F"
  params:  {"P1"=>""}
  depends:  ["DF1"]
  conflicts:  ["CF"]
  included_features:  ["IF1"]

# wallaby add-params-to-group g P1
Console Connection Established...
# wallaby show-group g
Console Connection Established...
Showing the following group: g
g
  name:  "g"
  membership:  ["n1", "n"]
  features:  ["F", "F1", "F2"]
  params:  {"P1"=>"0"}

This should probably be split into multiple bugs, some of which will wind up WONTFIX; assigning to Rob since these commands are his wheelhouse.
