-% Font management and installation has always been painful with \TeX\ (and even more with \LaTeX ). A lot of files are needed for one font (tfm, pfb, map, fd, vf), and they are limited to 256 characters. But the font world has evolved since, and new standard types of fonts have appeared, like \textsf{truetype} or \textsf{opentype} fonts. These fonts can contain a lot of characters, and have some functionalities (ligatures, old-style numbers, small capitals, etc.). They are everywhere, as the system fonts and most modern text softwares fonts are of this type. Until now the (almost) only way to use them with \TeX\ was to use them with Xe\TeX .

-% This package is a wrapper for several files taken from the Con\TeX t macro package. The philosophy is to let Con\TeX t do all the implementation and update these files from time to time. To do so we did not modify the files taken from Con\TeX t, we only changed their names to prevent name clashes. You can thus update the font system of this package simply by updating the files taken from Con\TeX t, without (theorically) changing the \texttt{.sty} file nor the main \texttt{.lua} file.
