This is the README for libertine, version 5.3.0 (2023-11-26). This package provides support for use of the Linux Libertine and Linux Biolinum families of fonts with LaTeX. Most features are usable with LaTeX and dvips, pdfLaTeX, xeLaTeX and luaLaTeX, but some features are only usable with xeLaTeX or luaLaTeX. This package compatibly replaces several earlier packages (libertine-type1, biolinum-type1, libertine) and should provide partial compatibility with the obsolete libertineotf and libertine-legacy packages. To install this package on a TDS-compliant TeX system download the file "tex-archive"/install/fonts/libertine.tds.zip, where the preferred URL for "tex-archive" is http://mirror.ctan.org. Unzip the archive at the root of an appropriate texmf tree, likely a personal or local tree. If necessary, update the file-name database (e.g., texhash texmf). Update the font-map files by enabling the Map file libertine.map. For most purposes, simply add \usepackage{libertine} to the preamble of your document. This will activate Libertine as the main (serifed) text font, Biolinum as the sans font and LibertineMono as the monospaced font. It is recommended that the font encoding be set to T1 or LY1, but the default OT1 encoding is also supported. Available shapes in all series (except tt) include: it italic sc small caps scit italic small caps Slanted variants are not supported; the designed italic variants will be automatically substituted. The exception is the bold series of Biolinum, for which a designed italic is not currently available. An artificially slanted variant has been generated and treated as if it were italic. To activate Libertine (without Biolinum), use the libertine (or rm) option. Similarly, to activate Biolinum (without Libertine), use the biolinum (or sf or ss) option. To use Biolinum as the main text font (as well as the sans font), use the option sfdefault. To suppress activating LibertineMono, use mono=false (or tt=false). To activate single font families, use one or more of \usepackage{libertineRoman} \usepackage{libertineMono} \usepackage{biolinum} For more advanced usage, please see the libertine.pdf document. For compatible mathematics, it is recommended to use \usepackage[libertine]{newtxmath} with [pdf]LaTeX and \usepackage{unicode-math} \setmathfont[Scale=MatchUppercase]{libertinusmath-regular.otf} with xeLaTeX or luaLaTeX. The original opentype fonts were created by Philipp H. Poll (gillian at linuxlibertine.org) and are licensed under the terms of the GNU General Public License (Version 2, with font exception) and under the terms of the Open Font License. For details look into the doc directory of the distribution or at http://www.linuxlibertine.org/ The Glyph and KeyCap support was adapted from the original libertine package by Michael Niedermair. Three of the Libertine fonts were modified by Michael Sharpe (msharpe at ucsd.edu) using fontforge to correct minor problems, including adding three missing ligatures (fl, ffl, ffi) to the bold-italic font. The type 1 fonts were created using cfftot1 or fontforge. The support files were created using autoinst. The support files are licensed under the terms of the LaTeX Project Public License.
