out in the wilderness, the daemon cries:

> The following information was provided by the package's contributor.
> Name of contribution: interval
> Author's name: Lars Madsen
> Package version:  0.1
> Location on CTAN: macros/latex/contrib/interval/
> Summary description: Provides a macro to format intervals, ensuring
>           the proper spacings around the fences 
> License type: lppl
> Announcement text given by the package's contributor:
> ----------------------------------------------------------------------
> When typing an open interval as $]a,b[$, a closing bracket is being
> used in place of an opening fence and vice verse. This leads the wrong
> spacing in, say, $]-a,b[$ or $A\in]a,b[=B$. This package attempts to
> solve this using 
> \interval{a}{b}            -> [a,b]
> \interval[open]{a}{b}      -> ]a,b[
> \interval[open left]{a}{b} -> ]a,b]
> etc.
> It also support fence scaling and ensure that the enclosing fences
> will end up having the proper closing and opening type.
