% Font management and installation has always been painful with \TeX.
-% A lot of files are needed for one font (tfm, pfb,
-% map, fd, vf), and as \TeX\ is 8-bit each font is limited to 256 characters.
-% But the font world has
-% evolved since \TeX, and new standard types of fonts have appeared, most
-% notably
-% \textsf{TrueType} and \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 only
