+\abstract
+
+The Fontconfig library provides for central administration and configuration
+of fonts in a POSIX system. All font consumers can share a common database
+of fonts and use common matching rules for font names. The set of available
+fonts can be configured for each user and a set of configurable matching
+rules allow for customizing the selection of fonts and configuring various
+parameters related to rasterizing of those fonts for display in a variety of
+media. The Fontconfig library is designed to co-exist peacefully with
+existing font configuration and rasterization mechanisms; while it uses the
+FreeType library to discover characteristics of available fonts, there
+is no requirement to use FreeType for rasterization.

+.SH NAME
+fontconfig \- Font configuration and customization library
+
+.SH SYNOPSIS
+.nf
+.B #include <fontconfig/fontconfig.h>
+.B #include <fontconfig/fcfreetype.h>
+.B #include <fontconfig/fcxml.h>
+.fi
+.SH DESCRIPTION
+.B Fontconfig
+is a library designed to provide system-wide font configuration,
+customization and application access.
+
+.SH FUNCTIONAL OVERVIEW
+Fontconfig contains two essential modules, the configuration module which
+builds an internal configuration from XML files and the matching module
+which accepts font patterns and returns the nearest matching font.
+
+.SS FONT CONFIGURATION
+The configuration module consists of the FcConfig datatype, libxml2 and
+FcConfigParse which walks over an XML tree and ammends a configuration with
+data found within. From an external perspective, configuration of the
+library consists of generating a valid XML tree and feeding that to
+FcConfigParse. The only other mechanism provided to applications for
+changing the running configuration is to add fonts and directories to the
+list of application-provided font files.
+.P
+The intent is to make font configurations relatively static, and shared by
+as many applications as possible. It is hoped that this will lead to more
+stable font selection when passing names from one application to another.
+XML was chosen as a configuration file format because it provides a format
+which is easy for external agents to edit while retaining the correct
+structure and syntax.
+.P
+Font configuration is separate from font matching; applications needing to
+do their own matching can access the available fonts from the library and
+perform private matching. The intent is to permit applications to pick and
+choose appropriate functionality from the library instead of forcing them to
+choose between this library and a private configuration mechanism. The hope
+is that this will ensure that configuration of fonts for all applications
+can be centralized in one place. Centralizing font configuration will make
+simplify and regularize font installation and customization.
+
+.SS FONT PROPERTIES
+While font patterns may contain essentially any properties, there are some
+well known properties with associated types. Fontconfig uses some of these
+properties for font matching and font completion. Others are provided as a
+convenience for the applications rendering mechanism.

+
+.SS FONT MATCHING
+Fontconfig performs matching by measuring the distance from a provided
+pattern to all of the available fonts in the system. The closest matching
+font is selected. This ensures that a font will always be returned, but
+doesn't ensure that it is anything like the requested pattern.
+.P
+Font matching starts with an application constructed pattern. The desired
+attributes of the resulting font are collected together in an FcPattern
+object. Each property of the pattern can contain one or more values; these
+are listed in priority order; matches earlier in the list are considered
+"closer" than matches later in the list.
+.P
+The initial pattern is modified by applying the list of editing instructions
+specific to patterns found in the configuration; each consists of a match
+predicate and a set of editing operations. They are executed in the order
+they appeared in the configuration. Each match causes the associated
+sequence of editing operations to be applied.
+.P
+After the pattern has been edited, a sequence of default substitutions are
+performed to canonicalize the set of available properties; this avoids the
+need for the lower layers to constantly provide default values for various
+font properties during rendering.
+.P
+The canonical font pattern is finally matched against all available fonts.
+The distance from the pattern to the font is measured for each of several
+properties: foundry, charset, antialias, family, spacing, pixelsize, style,
+slant, weight, rasterizer and outline. This list is in priority order --
+results of comparing earlier elements of this list weigh more heavily than
+later elements.
+.P
+The pattern representing that font is augmented to include any properties
+found in the pattern but not found in the font itself; this permits the
+application to pass rendering instructions or any other data through the
+matching system. Finally, the list of editing instructions specific to
+fonts found in the configuration are applied to the pattern. This modified
+pattern is returned to the application.
+.P
+The return value contains sufficient information to locate and rasterize the
+font, including the file name, pixel size and other rendering data. As
+none of the information involved pertains to the FreeType library,
+applications are free to use any rasterization engine or even to take
+the identified font file and access it directly.
+.P
+The match/edit sequences in the configuration are performed in two passes
+because there are essentially two different operations necessary -- the
+first is to modify how fonts are selected; aliasing families and adding
+suitable defaults. The second is to modify how the selected fonts are
+rasterized. Those must apply to the selected font, not the original pattern
+as false matches will often occur.
+.SS FONT NAMES
+Fontconfig provides a textual representation for patterns that the library
+can both accept and generate. The representation is in three parts, first a
+list of family names, second a list of point sizes and finally a list of
+additional properties:
+.nf
+ <families>-<point sizes>:<name1>=<values1>:<name2>=<values2>...
+.fi
+Values in a list are separated with commas. The name needn't include either
+families or point sizes; they can be elided. In addition, there are
+symbolic constants that simultaneously indicate both a name and a value.
+Here are some examples:
+.sp
+.nf
+.ta 1i 3i
+ Times-12 12 point Times Roman
+ Times-12:bold 12 point Times Bold
+ Courier:italic Courier Italic in the default size
+ Monospace:matrix=1 .1 0 1 The users preferred monospace font
+ with artificial obliquing

+.SS <or>
+.SS <and>
+.SS <plus>
+.SS <minus>
+.SS <times>
+.SS <divide>
+These elements perform the specified operation on a list of expression
+elements. <or> and <and> are boolean, not bitwise.
+.SS <eq>
+.SS <not_eq>
+.SS <less>
+.SS <less_eq>
+.SS <more>
+.SS <more_eq>
+These elements compare two values, producing a boolean result.
+.SS <not>
+Inverts the boolean sense of its one expression element
+.SS <if>
+This element takes three expression elements; if the value of the first is
+true, it produces the value of the second, otherwise it produces the value
+of the third.
+.SS <alias>
+Alias elements provide a shorthand notation for the set of common match
+operations needed to substitute one font family for another. They contain a
+<family> element followed by optional <prefer>, <accept> and <default>
+elements. Fonts matching the <family> element are edited to prepend the
+list of <prefer>ed families before the matching <family>, append the
+<accept>able familys after the matching <family> and append the <default>
+families to the end of the family list.
+.SS <family>
+Holds a single font family name
+.SS <prefer>
+.SS <accept>
+.SS <default>
+These hold a list of <family> elements to be used by the <alias> element.
