this is a redmine plugin. it is a issue template. the template is written in wiki.
generate issue(s) from wiki(s). Examples:\n\n<pre>{{wiki_to_issue(wiki_page_name)}}\n </pre> this will create a BUTTON to create new issue: subject=wiki_page_name.title, description=wiki_page_name.content, project=wiki_page_name.project, author=current_user. what's more, if wiki_page_name.content include <pre> :child_issue:[[wiki_page_name2]] </pre>, another child issue will be created. this child process could be a recursion. but the recursion depth is limited to 10.
