[Emacspeak] Pkgsrc package of Emacspeak

[adr <adr@xxxxxxx>]

First of all, hello to everyone.

I'm not visually impaired but I've been always interested in computer
interaction without sight. The sighted people around here knows
how different our brains behave when we close that window. Anyway,
I'm communicating with you to share a port I've made of Emacspeak
to pkgsrc. For those who don't know what pkgsrc is, it's a packaging
framework for unix-like systems used primarily by NetBSD.

I'm curious about EMACSPEAK_PLAY. Would not be better to use just
emacspeak-play-program and remove the use of that variable? Or use
just the variable? I don't understand the separation of the two of
them.

Sox is a dependency, and it's available in any unix-like system.
Why not use "play" as the default audio player?

Regards.
