Font configuration and customization library

[[TOC]]

Fontconfig can:

• discover new fonts when installed automatically, removing a common source of configuration problems.
• perform font name substitution, so that appropriate alternative fonts can be selected if fonts are missing.
• identify the set of fonts required to completely cover a set of languages.
• have GUI configuration tools built as it uses an XML-based configuration file (though with autodiscovery, we believe this need is minimized).
• efficiently and quickly find the fonts you need among the set of fonts you have installed, even if you have installed thousands of fonts, while minimizing memory usage.
• be used in concert with the X Render Extension and FreeType to implement high quality, anti-aliased and subpixel rendered text on a display.

Fontconfig does not:

• render the fonts themselves (this is left to FreeType or other rendering mechanisms)
• depend on the X Window System in any fashion, so that printer only applications do not have such dependencies
