I had difficulties in using UltiSnips, so I fear I installed it multiple times with different plugin managers.At the moment tree -d in .vim folder gives the following result, showing that I definitely dirtied the .vim folder, disseminating the same plugin all around (<------------- on lines where the string snip appears).. after  indent bundle  L9   autoload    l9   doc   plugin  ultisnips <-----------------------------------------------   after    plugin   autoload    neocomplete     sources    UltiSnips <-----------------------------------------------    unite        sources   ctags   doc    examples        autojump-if-empty        snippets-aliasing <-----------------------------------------------        tabstop-generation   ftdetect   ftplugin   plugin   pythonx    UltiSnips <-----------------------------------------------        snippet <-----------------------------------------------         definition         parsing         source             file        text_objects   rplugin    python3        deoplete            sources   syntax   test   utils  UltiSnips <-----------------------------------------------   after    plugin   autoload    neocomplete     sources    UltiSnips <-----------------------------------------------    unite        sources   ctags   doc   ftdetect   ftplugin   plugin   pythonx    UltiSnips <-----------------------------------------------        snippet <-----------------------------------------------         definition         parsing         source             file        text_objects   rplugin    python3        deoplete            sources   syntax   test   utils  vim-fugitive   doc   plugin  vim-latex   compiler   doc    db2vim   ftplugin    latex-suite        dictionaries        macros        packages        templates   indent   plugin  vim-snippets <-----------------------------------------------   autoload   plugin   pythonx   snippets <-----------------------------------------------    coffee    javascript   UltiSnips <-----------------------------------------------   vim-snippets <-----------------------------------------------       autoload       plugin       pythonx       snippets <-----------------------------------------------        coffee        javascript       UltiSnips <-----------------------------------------------  Vundle.vim      autoload       vundle      doc      ftplugin      syntax      test          files colors compiler doc  db2vim ftdetect ftplugin  latex-suite      dictionaries      macros      packages      templates indent plugin syntax ultisnips_rep <-----------------------------------------------     after      plugin     autoload      neocomplete       sources      UltiSnips <-----------------------------------------------      unite          sources     ctags     doc      examples          autojump-if-empty          snippets-aliasing <-----------------------------------------------          tabstop-generation     ftdetect     ftplugin     plugin     pythonx      UltiSnips <-----------------------------------------------          snippet <-----------------------------------------------           definition           parsing           source               file          text_objects     rplugin      python3          deoplete              sources     syntax     test     utils
