[External] Re: capture "->"
Dear Barry,
In general, I believe users are already accustomed with the classical
arrows "->" and "<-" which are used as such in quoted expressions.
But I agree that "-.>" is a very neat trick, thanks a lot. A small dot,
what a difference.
All the best,
Dmitri

How do we evaluate the summation of (1/m!) from 0 to infinity (for example).
Any help is very much appreciated.
Thank you.

[RFC] virtio-iommu version 0.4
This is the continuation of my proposal for virtio-iommu, the para-
virtualized IOMMU. Here is a summary of the changes since last time [1]:
* The virtio-iommu document now resembles an actual specification. It is
split into a formal description of the virtio device, and implementation
