FONTLOG Doulos SIL font family ======================== This file provides detailed information on the Doulos SIL font. This information should be distributed along with the Doulos SIL font and any derivative works. Basic Font Information ---------------------- Doulos is very similar to Times/Times New Roman, but only has a single face - regular. It is intended for use alongside other Times-like fonts where a range of styles (italic, bold) are not needed. The goal for this product was to provide a single Unicode-based font family that would contain a comprehensive inventory of glyphs needed for almost any Roman- or Cyrillic-based writing system, whether used for phonetic or orthographic needs. In addition, there is provision for other characters and symbols useful to linguists. This font makes use of state-of-the-art font technologies to support complex typographic issues, such as the need to position arbitrary combinations of base glyphs and diacritics optimally. One font from this typeface family is included in this release: * Doulos SIL Regular A Note Regarding the Open Font License and TypeTuner ---------------------------------------------------- The OFL prohibits the use of Reserved Font Names "Doulos" and "SIL" in the name of any font that is derived from the Original Version of Doulos SIL. However, SIL International (the Copyright Holder) grants through this separate written agreement the right to use the Reserved Font Names in any Modified Version of this font created by using TypeTuner as long as the feature information contained in the Original Version is used, unmodified, as the source for TypeTuner feature information, and "Doulos SIL" is not the resulting font family name. TypeTuner-produced fonts created in this manner are still bound by the terms of the OFL. Specifically, the use of Reserved Font Names is prohibited when making derivatives of a TypeTuner-produced font. Anyone making a derivative of a TypeTuner font will need to find a different name. For example a TypeTuner-produced font may be named "Doulos SIL Literacy SomeFarAwayPlace" but a derivative of that font made with other tools would not be allowed to use the "Doulos" and "SIL" Reserved Font Names and would have to be named something like "Servant Foo".

For information on what you're allowed to change or modify, consult the OFL and OFL-FAQ. Anyone can make their own modified version of Doulos SIL (using a different name), but SIL International will continue to maintain and develop the canonical version of the Doulos SIL font. As the package maintainer, we welcome contributions. Here are some things to keep in mind: Format: We are open to contributions in various formats, but if you want to maximise the chances of us including your work, please make it available to us (via email or a URL) as either a FontLab database (preferred) or a PostScript Type 1 (or OT-CFF) font. Source files: We are not yet making the extended source files available, because our build system is rather complex and difficult to reproduce. We hope to include an easier process in the future. Copyright attribution: If you submit something for inclusion in the main Doulos SIL fonts, we will ask you to affirm that it is your original work, and ask you to assign the copyright of your work to SIL International. This is to ensure that future releases can be made under improved versions of the OFL without needing to track you down for further permission. This follows the same principle used by the FSF. Keep in mind that we are a not-for-profit organization committed to free/libre and open source software, and that any contributions incorporated in the fonts will always be available under the OFL or a similar license. Quality: Because we want to be able to guarantee a high level of quality for the primary Doulos SIL font, we will review submissions carefully. Please don't be discouraged if we do not include a submission for this reason, or ask you to make specific revisions. Types of contributions: If you wish to make a contribution - a set of additional glyphs, scripts, code, etc. - please contact us before you do any work to see if it is a contribution we currently need. Every addition adds to the complexity of the project and needs to be carefully planned. This also avoids two people working on the same type of addition at the same time. Linux packages: Please contact the upstream maintainer of the various packages - nicolas_spalinger@sil.org - if you want to help package or maintain a package. When submissions will be included: We plan to revise the fonts when major updates are needed (eg new versions of Unicode). If you wish to make submissions, contact us on the timing.
