This is the README for the arimo package, version 2022-09-28. This package provides LaTeX, pdfLaTeX, XeLaTeX and LuaLaTeX support for the Arimo family of fonts, designed by Steve Matteson. Arimo is an innovative, refreshing sans serif design that is metrically compatible with Arial. Arimo offers improved on-screen readability characteristics and the pan-European WGL character set and solves the needs of developers looking for width-compatible fonts to address document portability across platforms. To install this package on a TDS-compliant TeX system download the file "tex-archive"/install/fonts/arimo.tds.zip where the preferred URL for "tex-archive" is http://mirrors.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). Update the font-map files by enabling the Map file arimo.map. To use, add \usepackage{arimo} to the preamble of your document. These will activate Arimo as the sans serif text font. Use the sfdefault option to make sans-serif fonts the default. LuaLaTeX and xeLaTeX users who might prefer type1 fonts or who wish to avoid fontspec may use the type1 option. Options scaled= or scale= may be used to scale the fonts. Font encodings supported are OT1, T1, LY1 and TS1. TrueType fonts were obtained from https://fonts.google.com and are licensed under the Apache License, version 2; the text may be found in the doc directory. The support files were created using autoinst and are licensed under the terms of the LaTeX Project Public License. The maintainer of this package is Bob Tennent (rdt at cs.queensu.ca)
