tex4ht – Con­vert (La)TeX to HTML/XML

A con­verter from TeX and LaTeX to SGML-based for­mats such as (X)HTML, MathML, OpenDoc­u­ment, and DocBook, pro­vid­ing a con­fig­urable (La)TeX-based au­thor­ing sys­tem for hy­per­text.
Tex4ht does not parse (La)TeX source (so that it avoids the dif­fi­cul­ties en­coun­tered by many other con­vert­ers, aris­ing from the ir­reg­u­lar­ity of (La)TeX syn­tax). In­stead, Tex4ht uses (La)TeX it­self (with an ex­tra macro pack­age) to pro­duce a non-stan­dard DVI file that it can then pro­cess. This tech­nique al­lows TeX4ht to ap­proach the ro­bust­ness char­ac­ter­is­tic of re­stricted-syn­tax sys­tems such as hy­per­la­tex and gellmu.
Note that CTAN no longer holds the defini­tive sources of the pack­age: see the ‘Readme’ file.
