.SH NAME
cthulhu \- a scriptable screen reader
.SH SYNOPSIS

.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.
