larsimmisch df89c12581 Decided that getenum should return the selected item and the available
items.

Argument parsing errors are reported with the methodname (minor 
improvement).

Smallish documentation improvements.

1 What is ALSA</a>
</h1>
<p>
The Advanced Linux Sound Architecture (ALSA) provides audio and MIDI
functionality to the Linux operating system.
<p>
Logically ALSA consists of these components:
<ul>
<li>A set of kernel drivers.
<br>
These drivers are responsible for handling the physical sound
hardware from within the Linux kernel, and have been the standard
sound implementation in Linux since kernel version 2.5
</li>
<li>A kernel level API for manipulating the ALSA devices.
</li>
<li>A user-space C library for simplified access to the sound hardware
from userspace applications. This library is called <i>libasound</i>
and is required by all ALSA capable applications.
</li>
</ul>
<p>
More information about ALSA may be found on the project homepage
