What is `liblouis.x86_64`

Liblouis is an open-source braille translator and back-translator named in honor of Louis Braille. It features support for computer and literary braille, supports contracted and uncontracted translation for many languages and has support for hyphenation. New languages can easily be added through tables that support a rule- or dictionary based approach. Liblouis also supports math braille (Nemeth and Marburg). Liblouis has features to support screen-reading programs. This has led to its use in two open-source screen readers, NVDA and Orca. It is also used in some commercial assistive technology applications for example by ViewPlus. Liblouis is based on the translation routines in the BRLTTY screen reader for Linux. It has, however, gone far beyond these routines.
