EncTeX is original work of Petra Olšák from year 1997. Since this time re-encoding feature was become standard part of most TeX distributions, so EncTeX is no nonger maintained. But for small community of people preparing for example Czech/French bi-linguas, it could be still more effective way than standard web2c. So I decided to port EncTeX to latest web2c.
Latest version can be found at http://www.penguin.cz/~utx/ftp/tex/, original version (with further data) at ftp://ftp.cstug.cz/pub/local/cstug/olsak/enctex/.
