Improve documentation: add graphviz graph
Via email from poc senderi, the documentation could be improved via a graph from graphviz:
digraph po_debconf_manager {
pending_translation -> being_translated [label="wanna translate"];
being_translated -> pending_translation [label="give up, save changes"];
being_translated -> pending_translation [label="give up, discard changes"];
being_translated -> pending_review [label="translation finished"]
pending_review -> being_reviewed [label="wanna review"];
being_reviewed -> pending_upstreaming [label="review finished"]
being_reviewed -> pending_review [label="give up, save changes"]
being_reviewed -> pending_review [label="give up, discard changes"]
pending_upstreaming -> waiting_merge;
}Could be generated online:
