-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.
