VSliTeX – Vir­tual in­vis­i­ble fonts for use with LaTeX Slides class

The LaTeX 2.09-based pro­gram SliTeX, and the cor­re­spond­ing LaTeX slides class, use in­vis­i­ble fonts when pro­duc­ing multi-coloured over­lays on foils. SliTeX dis­tri­bu­tions in­cluded a set of in­vis­i­ble ver­sions of the Meta­font sources of the Com­puter Modern fonts (an odd con­cept, but it worked). The present bun­dle pro­vides a (some­what more in­tel­lec­tu­ally sat­is­fy­ing) set of vir­tual fonts that pro­vide the same in­for­ma­tion (i.e., ef­fec­tively met­rics only) with­out the need to com­pile a Meta­font source to get it.
