[NTG-context] How to achieve a LaTeX-center-like thing

2011-09-06 Thread Marcin Borkowski 
Hi,

I'd like to have something like this:

  Let $X$ be a~real Banach space, $D$~an open subset of~$X$
  containing~$0$ and $T$ a~continuous mapping from $\overbar{D}$
  to~$X$.  We say that $T$ satisfies the {\em Mönch condition} if the
  following implication holds:
  \blank[small]
  \startalignment[middle]
If $C\subset\overbar{D}$ is countable and
$C\subset\clconv\bigl(\{0\}\cup F(C)\bigr)$, then
$\overbar{C}$ is compact.
  \stopalignment
  \blank[small]

Is there any option for alignment which would enable me not to put the
blanks manually?

TIA,
