2 'unixtex.ftp': Obtaining TeX
******************************
This is <ftp://tug.org/tex/unixtex.ftp>, a.k.a.
<https://tug.org/unixtex.ftp>, last updated 29 February 2020. Email
<tex-k@tug.org> with comments or questions.
The principal free TeX distribution for Unix-like systems is TeX
Live, on the web at <http://tug.org/texlive>. The pages there describe
many ways to acquire and/or build TeX, over the Internet or on physical
media, both the sources and precompiled binaries for many systems,
either standalone or as part of various operating system distributions.
Web2c, Kpathsea, Dvips, and Dviljk, among others, are no longer
released as a separate packages. Their sources are now maintained as
part of TeX Live.
The host ftp.cs.stanford.edu is the original source for the files for
which Donald Knuth is directly responsible: 'tex.web', 'plain.tex', etc.
However, unless you want to undertake the project of building your TeX
system from scratch, it is more reliable and less work to retrieve these
files as part of a larger package.
In any case, the Stanford ftp site is not the canonical source for
anything except what was created as part of Knuth's original TeX, so do
not rely on any other files available there being up-to-date. The best
place to check for up-to-date files is CTAN (the Comprehensive TeX
Archive Network), <https://ctan.org>.
