There is part of the output:
What does the symbols ('+','\','->','()','(*)') exactly mean?
Opal
+, -, | and \ are just used to draw the tree - it's a kind of ASCII art.
When it comes to (*) and -> please refer to this question and answer.
tl;dr
(*) - is used to indicate that particular dependency is described somewhere else in the tree
-> - is used to point the dependency that wins in version conflict.
