    A problem may arise if the user is not an administrator and TeX already exists in the search path. Since the effective search path consists of the system search path followed by the user search path, the new TeX Live would never get precedence. As a fallback, the installer creates a shortcut to the command-prompt in which the new TeX Live binary directory is prepended to the local search path. The new TeX Live will be always usable from within such a command-prompt. The shortcut for TeXworks, if installed, also prepends TeX Live to the search path, so it should also be immune to this path problem. -

    A bit of history: The original implementation was by Tomas Rokicki who, in 1987, developed a first TeX-to-C system based on change files under Unix, which were primarily the original work of Howard Trickey and Pavel Curtis. Tim Morgan became the maintainer of the system, and during this period the name changed to Web-to-C. In 1990, Karl Berry took over the work, assisted by dozens of additional contributors, and in 1997 he handed the baton to Olaf Weber, who returned it to Karl in 2006. -

    We call a search path a colon- or semicolon-separated list of path elements, which are basically directory names. A search path can come from (a combination of) many sources.

A complete draft of the TDS was published in the December 1995 issue of TUGboat, and it was clear from an early stage that one desirable product would be a model structure on CD.

It was also clear that the success of the 4AllTeX CD showed that Unix users would benefit from a similarly easy system, and this is the other main strand of TeX Live. -
