[InvTarget::] Final Inventory.
|

|
|
To print a summary of the contents of a repository.
|

|
@ This target is fairly simple: when we get the message to begin generation,
|
|
we simply ask the Inter module to output some text, and return true to
|
|
tell the generator that nothing more need be done.
