读取语音邮件的程序。联合vgetty和USR Modem使用

/*

   Voice Reader version 0.1 (Very Alpha)

   This is my very first attempt at using the qt library.  I decided to write
   a little application that I can use to listen to voice mail messages recieved
   with vgetty.  Since I have a USR voice modem which uses GSM as its audio 
   format it is relatively easy to translate that into au format and send to 
   /dev/audio.  Since other voice modems use other formats besides GSM, more work
   will need to be done on those to convert the format to be /dev/audio playable.
   This version is extremely simple (written in <1 hour) but it gives something
   to work on.  This package was compiled using gtk+-0.99.9 and the gsm library.
   I use untoast in a system call specifically to translate the GSM formated 
   voice file into au format and then push it's output into /dev/audio.

   I am not including the gsm library as part of this package, it will need
   to be downloaded seperately.  And it is only useful if you have a newer
   USR voice modem.  This program works well with vgetty, but could be modified
   easily to work with other programs as well.

   This code is licenced under the terms of the GPL.  If you make changes to
   this code (as I hope many will) all I ask is that you send a copy to me
   so that I can incorporate it into the next release.  And if it works well
   for you I would also like to hear about it.

   If you have any suggestions I am always open to them.  Since this is a first
   attempt and many things need to be changed I would appreciate input. 
   
   Please send questions or suggestions to [e-mail].

   Thanks.
