Note: This file was written with only two purposes in mind:
    o To test the program upon it
    o To show off some of the features

Most  of  the  does  thus  consist  of  lots  of pseudo-commands, which are
nonsense in a TeXnical manner.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

This should give us a warning \ref{foo}, but this should not~\ref{foo}.

\this should give us errors. $\this should not$. $$\neither should this$$.
\(This is \also legal\). However, \this is not. Errors should also not
be given when the command is ended by a \comma, or likewise. We will also
not react on `silent' commands like this \bf one.

Tries to look after incorrect hyphenation - that one had an incorrect
length -- so had that one.  However, the following ones are correct, even
though we've made 2--3 errors --- easy-peasy, or what? That should indeed
not be written as: ...made 2-3 errors -- easy--peasy, or what?

Furthermore, some uses of abbrevs should be reacted on, i.e. that one. We'll
just making sure that interword spacing is enforced, i.e.\ like that.

Certain types of punctuation may be doubtful, like THIS ONE! That one should
have been written as THIS\@. See?

We'll also check accents. Examples of correct and wrong:
\"{a} \"{b} \"{i} \'{{i}} \"{\i} $\hat{i} \tilde{\imath}$

However, this will not work well currently: \"
{i}

We'll also test the {\em emphasise}, it should be written as {\em emphasise\/}.
Don't use \/ elsewhere, please, not twice either {\em like\/ this\/.

We will normally also wipe the contents of all `\verb@\verb@' commands. Thus
will this give no faults: \verb@)[35}[) \LaTeX i.e. \bf \ref, just - errors@.
However, this will indeed: @)[35}[) \LaTeX i.e. \bf \ref, just - errors.
Currently, we choke on this: \verb@

We will also report this: $(x^2 + 1)^3 + \{x^2 + 4\}^6$, which should be written
like this: ${(x^2 + 1)}^3 + {\{x^2 + 4\}}^6$

% Of course, `errors' in comments are fully ignored, \like this.
\% \This is thus detected, % \this is not.

\makeatletter \@yet another test \makeatother

\@But this works!

Finally, let's match some brackets.

We should also kick on this: " ´, both excellent examples of which quotes _not_
to use.

\this\, on the other hand,  is a new kind of error for 1.2; specifically
introduced as a friend of mine kept on making such mistakes. (It should have
been \this, as you may see --- he thought that _all_ \LaTeX\ commands had 
to end with a backslash...)

Some maths: $10^10$ $2^2_n$ $10^{10}$

```Can you get your quotes right', he said''.

Example of a 'user' pattern we'll search for: \unknown

Okay, that's about it, I guess...have fun.
