TeX – A so­phis­ti­cated type­set­ting en­gine

TeX is a type­set­ting sys­tem that in­cor­po­rates a macro pro­ces­sor. A TeX source doc­u­ment spec­i­fies or in­cor­po­rates a num­ber of macro def­i­ni­tions that in­struct the TeX en­gine how to type­set the doc­u­ment. The TeX en­gine also uses font met­rics gen­er­ated by Meta­font, or by any of sev­eral other mech­a­nisms that in­cor­po­rate fonts from other sources into an en­vi­ron­ment suit­able for TeX.
TeX has been, and con­tin­ues, a ba­sis and an in­spi­ra­tion for sev­eral other pro­grams, in­clud­ing e-TeX and PDFTeX.
The dis­tri­bu­tion in­cludes the source of Knuth’s TeX book; this source is there to read, as an ex­am­ple of writ­ing TeX — it should not be pro­cessed with­out Knuth’s di­rect per­mis­sion.
