TeX

TeX is a type­set­ting pro­gram de­signed for high-qual­ity com­po­si­tion of ma­te­rial that con­tains a lot of math­e­mat­i­cal and tech­ni­cal ex­pres­sions. It has been adopted by many au­thors and pub­lish­ers who gen­er­ate tech­ni­cal books and pa­pers. It was cre­ated by Pro­fes­sor Don­ald Knuth of Stan­ford Univer­sity, orig­i­nally for prepa­ra­tion of his book se­ries “The Art of Com­puter Pro­gram­ming”. TeX has been made freely avail­able by Knuth.

From these ori­gins a whole eco-sys­tem of dis­tri­bu­tions, macro pack­ages, and sup­port­ing pro­grams has arosen.
