在 Feather 主题的页脚行中添加 ## 的帧编号

Question

我的代码是：

\documentclass[10pt]{beamer}

\usetheme[]{Feather}
\setbeamercolor{structure}{fg=black}
\setbeamercolor{normal text}{fg=black,bg=white}

\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage[T1]{fontenc}
\usepackage{helvet}

\newcommand{\chref}[2]{
  \href{#1}{{\usebeamercolor[bg]{Feather}#2}}}

\title[The title] {\textbf{The extended title}}

\author[Name]{Name \\
      {\small Afilliation\\ Company}}

\institute[Institute]{Institute\\}

\date{ }

\begin{document}

{\1
\begin{frame}[plain, noframenumbering]
  \titlepage
\end{frame}
}

\begin{frame}{Content}{}
\tableofcontents
\end{frame}

%-------------------------------------------------------
\section{Introduction}

%-------------------------------------------------------
\section{Installation}
%-------------------------------------------------------
\subsection{Source files}
\begin{frame}{Installation}{Source files}
%-------------------------------------------------------

\begin{block}{}
The theme contains 4 source files:
  \begin{itemize}
    \item {\tt beamercolorthemeFeather.sty}
    \item {\tt beamerouterthemeFeather.sty}
    \item {\tt beamerinnerthemeFeather.sty}
    \item {\tt beamerthemeFeather.sty}
  \end{itemize}
\end{block}
\end{frame}


\begin{frame}{User Interface}{Loading the Theme and Theme Options}

  \begin{block}{The Color Theme}
    Also you can load only the color theme by writing in the preamble of the {\tt tex} file

    \vspace{5pt}

    \begin{itemize}
    \item {\tt \textbackslash usecolortheme\{Feather\}}
    \end{itemize}

    \vspace{5pt}

    ...or to change the colors of the various elements in the theme

    \vspace{5pt}
    \begin{itemize}
    \item Change the bar colors: \\
    {\tt \textbackslash setbeamercolor \{Feather\}\{fg=<color>, bg=<color>\}}

    \vspace{2pt}

    \item Change the color of the structural elements: \\
    {\tt \textbackslash setbeamercolor\{structure\}\{fg=<color>\}}

    \vspace{2pt}

    \item Change the frame title text color:\\
    {\tt \textbackslash setbeamercolor\{frametitle\}\{fg=<color>\}}

    \vspace{2pt}

    \item Change the normal text color background:
    {\tt \textbackslash setbeamercolor\{normal text\}\{fg=<color>, bg=<color>\}}
    \end{itemize}
  \end{block}
\end{frame}


%-------------------------------------------------------
\subsection{Feather image}
\begin{frame}{User Interface}{The Feather Background Image}
%-------------------------------------------------------

\begin{block}{The Feather Background Image}
    \begin{itemize}
    \item In Feather theme, the title page frame and the last frame have the Feather image as the background image.
    \item The Feather background image can be produced to any frame by writting on the begining at the chosen frame the following
    \end{itemize}

    \vspace{5pt}

  {\tt \{\textbackslash 1bg\\
    \textbackslash begin\{frame\}[<options>]\{Frame Title\}\{Frame Subtitle\}\\
    \ldots\\
    \textbackslash end\{frame\}\}}
\end{block}
\end{frame}


{\1
\begin{frame}[plain, noframenumbering]
  \finalpage{Thank you for using Feather Beamer Theme!}
\end{frame}}

\end{document} 

输出的一帧是：

。

如何在每个页脚行的右侧添加框架编号 #/##（例如 12 个中的 3 个），第一页和最后一页除外（例如在 Boadilla 主题中）：）？
