[chef] List all tags

[< >]

Is there an easy/efficient way to list all the tags rather than the list of
tags for a given node(s)? I suppose I could list all the tags for all nodes 
and
build a unique list of those.

Apologies for this naive question because I am new to Chef and Ruby but I
failed to find an answer via on-line search of Chef documentation and the
mailing list archive. Thanks.
