@intro<-section{Intro}

At-syntax is used to call a Haskell function. The result can be bound.
For example, the @sf{section} command returns a label that can be used
for references.

This is section @xref(intro). Note that cross-references are checked
at ``compile-time''. Forward references also work (see
sec. @xref(concl)).

@section{Markup}

Here comes @sf{some sans-serif text with @em{emphasis}!}

Note that arguments put in braces are markup.


@section{Math}

Arguments in parenthesis are Haskell. Combined with unicode syntax,
this can make writing all sorts of mathy stuff rather pleasant. For
example: @math(γ ⊢ x ∶ a).

The operators are overloaded to work on text as well:
@displayMath(b ≜ sqrt (a + (x/y)))


@concl<-section{Conclusion}



Marχup is awesome.
