'unixtex.ftp': Obtaining TeX **************************** This is , a.k.a. , last updated 29 February 2020. Email with comments or questions. The principal free TeX distribution for Unix-like systems is TeX Live, on the web at . 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), .
