WYSIWYM (What You See Is What You Mean) document processor
LyX is a document processor that encourages an approach to writing
based on the structure of your documents, not their appearance. The
author can concentrate on the content (What You See Is What You Mean).
The formatting is done by the backends (like LaTeX) and the output can
have different formats, such as DVI, postscript, PDF, html.
LyX can check the LaTeX installation by opening the LaTeX Configuration
document under "Help" on the menubar.
LyX uses ImageMagick to deal with images. For security reasons
(open)SUSE limits the functionaly of ImageMagick. See README.SUSE
(in /usr/share/doc/packages/lyx/) for more information.
There is no official package available for openSUSE Leap 15.4
