[1 <text/plain; us-ascii (7bit)>]
Hello,
Post by Samuel ThibaultI'd also rather see it tested in the real wild before committing. Could
somebody on the speakup mailing list test the patch? (which I have
re-attached as a file for conveniency).
Anybody up for testing please?
If people want to see speakup get mainlined instead of staging, please
help.
Samuel
