texbook.tex 编译

直接编译不能通过，要修改前四行

\loop\iftrue
  \errmessage{This manual is copyrighted and should not be TeXed}\repeat
\pausing1 \input manmac
\ifproofmode\message{Proof mode is on!}\pausing1\fi

改为

%\loop\iftrue                                                              % 注释掉
%  \errmessage{This manual is copyrighted and should not be TeXed}\repeat  % 注释掉
\input manmac 
%\ifproofmode\message{Proof mode is on!}\pausing1\fi                       % 注释掉

用tex命令编译
