+Extract title from external links~
+
+It is possible to automagically extract the title of a web page to create a
+link. The function #vimwiki#base#linkify() will get the URL under the cursor
+and replace the url with a markdown link.
+
+If the URL cannot be retrieved, nothing is changed.
+If the <title> html tag cannot be extracted, the url is used as the link
+title.

+Suggested mapping: >
+  nnoremap <silent> <leader>uu :call vimwiki#base#linkify()<cr>
