Elementary question

Hi all.

It's my first post on this list and I must first apologie for my poor
english.

I'm using gnu/linux since about twelve years and I plane to move from
debian/testing that I'd always used to slackware because of systemd. But
before doing this, I'd like to ask a elementary question.

Being blind, I first want to know if installation is accessible, that is to
say, does brltty is part of the packages? I didn't found it in the list of
the packages (slackware64) but maybe I'm wrong? I'd like to install by
myself without the help of a sighted person. Somewhere (but I cann't
remember where) I saw that speakup was present but I don't know if it speak
french...

Thanks for your answers.
