.SH SYNOPSIS
|
|
.B cthulhu
|
|
.RI [ option... ]
|
|
.SH DESCRIPTION
|
|
.B cthulhu
|
|
is a screen reader for people with visual impairments,
|
|
it provides alternative access to the desktop by using speech synthesis and braille.
|
|
.P
|
|
.B cthulhu
|
|
works with applications and toolkits that support
|
|
the Assistive Technology Service Provider Interface (AT-SPI), which
|
|
is the primary assistive technology infrastructure for Linux and
|
|
Solaris. Applications and toolkits supporting the AT-SPI include the
|
|
GNOME Gtk+ toolkit, the Java platform's Swing toolkit, LibreOffice,
|
|
Gecko, and WebKitGtk. AT-SPI support for the KDE Qt toolkit is being
|
|
pursued.
