Re: [Fwd: Emacspeak with doubletalk LT. "process speaker not running" on gentoo]

[Gary Gatling <gsgatlin@xxxxxxxxxxx>]

Thank you for the information. We are providing Emacspeak to students on 
our Red Hat Linux lab machines at North Carolina State University and we 
use doubletalk LT. here with it because they could still be purchased 
from the manufacturer. This information might be useful to us when RHEL 5 
comes out.

(Running RHEL 4 this semester)

Cheers,
