This file documents the installation of the LX fonts, version 2.0, extracted from file lxfonts-tds.zip. Of course you don't have to install anything if your TeX system already contains these LX fonts. Verify by searching the file lxfonts.sty in the texmf-dist rooted tree of your distribution; if it exists, you probably can skip reading the rest of this file. This archive contains three main directories tex/ fonts/ and doc/ each containing a TDS compliant folder or directory structure; TDS stands for: "TeX Directory Structure". Upon opening the compressed file extract or drag the contents of each main directory to the homonymous folder in you personal/local texmf tree, that, of course, should already be TDS compliant; if your operating system is not so smart to add the new files to existing TDS branches of the personal or local or system wide TDS tree, just copy or drag only the end twigs of these distributed branches. The use of a personal tree is suggested in order to avoid the need of reloading everything every time you upgrade your TeX system; in any case, should any upgrade already contain the LX fonts, check if the upgrade contains a more recent version of these fonts and related software; should it be the case, delete your personal installation and use the distributed one. Refresh the filename database; this operation depends from the particular distribution of the TeX system; on a Mac OS X, where the root of your personal texmf is ~/Library/texmf, the filename database does not need an explcit refresh. On other UNIX systems, where TeXlive is the TeX system distribution, you need to refresh the file name database by running texhash. On win32 platforms, if you use the MiKTeX distribution, open the MiKTeX Options from the Start dialog box and click the Refresh button. Similar operations must be performed with other TeX distributions. At this point the line Map lxfonts.map or, at your choice, Mixedmap lxfonts.map should be added to one of the updmap.cfg, files, but this operation should be done only by means of programs available with your TeX system distribution; therefore read the documentation of your TeX system and follow the suitable instructions very carefully. Always following the decumentations of your TeX system distribution rebuild the overall font maps necessary for all programs that use Type 1 fonts; with a TeX Live distribution it would be necessary to run the program updmap (as a single user) or updmap-sys (as an administrator or super user) depending on the operating system. Notice that this operation is substantially the same with every distribution and every operating system, but the details vary from platform to platform; therefore, again, read the documentation of your TeX system so as to proceed as required for your particular distribution. WORTH NOTING: Once the system wide or local maps files contain the names of the various LX type 1 fonts, it is irrelevant if you had specified Map or MixedMap, because the Type 1 ones will be always preferred to the METAFONT bitmapped fonts. But since this distribution contains also the METAFONT sources, it does not hurt to specify MixedMap. Actually the METAFONT sources are available in case you spotted some errors and you wanted to try your chance to correct them; when you've got the good corrections, please, don't forget to notify me! If you did everything correctly, your TeX system is now capable of using the LX fonts with LaTeX and with pdflatex, and dvips and dvipdfm can perform their specific transformations by using the PostScript forms of these LX fonts. Warning: load the lxfonts.sty file in your document preamble *after* any other call to font related packages simply with \usepackage{lxfonts} Read the demo pdf file to see how to use these fonts. Of course the slides production software may be any class or package that produces slides; it not necessary to use the same package used in the example. All you need for using these fonts is already contained in the correct installation of the files extracted from this lxfonts-tds.zip file. If you have a complete TeX system distribution, which is always preferable to a basic or incomplete one, you don't have to do anything because all fonts and necessary files are already installed.
