According to the GPL, the files must be delivered with +intact notifications of the license, and of where to get the original source +files. Furthermore, if the files are modified in any way, a notice must be +delivered of who modified the files on what date, and what modifications +were made. + +The licensed release font binary files as packaged on the GNU FreeFont +download page have embedded within them the license and origin notices +required to re-distribute them unmodified. + +Software for reading the contents of font files is readily available for +anybody who wishes to look at the embedded notices. + +Using the fonts without modifications +------------------------------------- + +If you simply distribute the TrueType, OpenType, or WOFF files of licensed +releases as packaged at the GNU FreeFont download site, the requirements of +the GPL are already fulfilled. + +Modifying the fonts for use as Web fonts +---------------------------------------- + +You may wish to modify the fonts for use as web fonts. + +For example, perhaps your site needs only a portion of the font's glyphs. +As the fonts are very large, it may improve loading speed very much to +cut out unneeded parts of the font. + +If you provide modified versions of the fonts, you must take care to +satisfy the GPL stipulation that two kinds of notices must be provided +with any distribution of FreeFont. These are + 1) the original GPL license and notifications of origin + 2) a description of modifications made to the font: who, when, what. +This information *must* be present in the font binary files delivered +from the web site. + +There is more than one way to satisfy the GPL. +The simplest strategy would be the following: + +Leave undisturbed the original "TTF Names" fields of the licensed release +font binaries: + Version + Copyright + Manufacturer + Vendor + Vendor URL + License + License URL + +In the font file's "TTF Names" field with ID "Descriptor", append text +indicating + * who performed the modifications, and their contact information + * date of modifications + * outline of what was modified +For example: + Modified Oct. 2011 by Steve White <stevan.white@gmail.com> + Most character ranges besides Latin were removed. + +If you do more than simply trim away character ranges from the font, +we at the FreeFont project we would ask you to + * append your own copyright notice to the Copyright field + * change the Version string to your own + * change Vendor and Vendor URL to your own name and URL. +(We don't want to be getting bug reports on your modifications!) + +$Id: webfont_guidelines.txt 2221 2012-04-16 22:45:30Z Stevan_White $ |
