lyx – Document processor based on LaTeX

LyX is an open source doc­u­ment pro­ces­sor that en­cour­ages an ap­proach to writ­ing based on the struc­ture of your doc­u­ments, not their ap­pear­ance. LyX lets you con­cen­trate on writ­ing, leav­ing de­tails of vi­sual lay­out to the soft­ware.
LyX pro­duces its out­put us­ing LaTeX in the back­ground; LyX is far more than a front-end to LaTeX, how­ever. No knowl­edge of LaTeX is nec­es­sary to use LyX, but such knowl­edge some­times helps ex­plain the way LyX is be­hav­ing.
LyX is not pro­vided on CTAN; po­ten­tial users should go to the LyX home page for more in­for­ma­tion.
