-Sometimes, when you are running (La)TeX, it will abruptly stop and 
-present you with a prompt (by default, just a `*` character). ​ Many 
-people (including this author) will reflexively hit the "​return"​ 
-key, pretty much immediately,​ and of course this is no help at all&​nbsp;&​mdash;​ 
-TeX just says: 
-```latex 
-(Please type a command or say `\end'​) 
-``` 
-and prompts you again. 
- 
-What's happened is that your (La)TeX file has finished prematurely,​ 
-and TeX has fallen back to a supposed including file, from the 
-terminal. ​ This could have happened simply because you've omitted 
-the `\bye` (Plain TeX), `\end{document}` (LaTeX), or 
-whatever. ​ Other common errors are failure to close the braces round a 
-command'​s argument, or (in LaTeX) failure to close a verbatim 
-environment:​ in such cases you've already read and accepted an 
-error message about encountering end of file while scanning something. 
- 
-If the error is indeed because you've forgotten to end your document, 
-you can insert the missing text: if you're running Plain TeX, the 
-advice, to "say `\end`"​ is good enough: it will kill the run; if 
-you're running LaTeX, the argument will be necessary: 
-`\end{document}`.  ​ 
- 
-However, as often as not this isn't the problem, and (short of 
-debugging the source of the document before ending) brute force is 
-probably necessary. ​ Excessive force (killing the job that's 
-running TeX) is to be avoided: there may well be evidence in the 
-`log` file that will be useful in determining what the 
-problem is&​nbsp;&​mdash;​ so the aim is to persuade TeX to shut itself down 
-and hence flush all log output to file. 
- 
-If you can persuade TeX to read it, an end-of-file indication 
-(control-`D` under Unix, control-`Z` under Windows) will provoke 
-TeX to report an error and exit immediately. ​ Otherwise you should 
-attempt to provoke an error dialogue, from which you can exit (using 
-the `x` "​command"​). ​ An accessible error could well be inserting an 
-illegal character: what it is will depend on what macros you are 
-running. ​ If you can't make that work, try a silly command name or 
-two.
