LyX typesets what you enter as you enter it, in a way very similar to the way TeX typesets documents. When they print, LyX creates a LaTeX input file and uses the full power of LaTeX to typeset the document. Users need not worry about page breaks, page setup, etc. LaTeX is packed with knowledge about typography, and it takes care of those details. I installed it on a Sun Solaris machine and my home Linux machine.
Installation is very simple.
The installation script finds your LaTeX installation and other optional software like Perl and Ispell, and sets up LyX accordingly. You can reconfigure LyX at any time if you add or remove optional software. It uses Ghostscript , the free PostScript viewer, to render embedded encapsulated PostScript images. In fact, the integration of the various components is very impressive. This exemplifies the power of the UNIX process paradigm.
