About OpenHAL
OpenHAL is low-level interface software for Atheros 802.11 wireless

cards. Previously, Linux-based systems needed a proprietary Hardware

Abstraction Layer (HAL) plus a wrapper driver to make use of these

wireless cards. OpenHAL is a free and open source replacement for

the proprietary HAL. OpenHAL was initially based on ar5k, which was

used as the basis for a proprietary HAL replacement for the OpenBSD

project. Support for Atheros cards is important for Linux, as Atheros

wireless chipsets are commonly used by many device manufacturers.

----------------------
Do  fix this.  The grammar is highly ambiguous. It makes it look as

if ar5k is *proprietary* code, whereas it is, obviously, free code

under a BSD licence.
Oh, and by the way, if you actually care about software freedom,

you should write that
`Support for Atheros cards is important for open source OSes.'
Your current paragraph makes it look as if anything that's not linux

does not matter at all for you... which is nothing short of completely

insulting for every *other* free operating system out there.
