+\page rbtdeconfig_compiler The KDE Configuration Compiler for Ruby
+
+rbtdeconfig_compiler generates Ruby source code from an XML file containing 
+information about configuration options (.kcfg) and a file that provides 
+the code generation options (.kcfgc) The generated class is based on 
+KDE::ConfigSkeleton and provides an API for the application to access its
+configuration data.
+
+<h2>XML description of the configuration options</h2>
+
+The structure of the .kcfg file is described by its DTD kcfg.dtd.
+
+The \<kcfgfile\> tag contains the name of the configuration file described.
+Omitting the name will make the generated class use the default configuration
+file ("<appname>rc").
+
+The remaining entries in the XML file are grouped by the tag \<group\> 
+which describes the corresponding group in the configuration file.
+
+The individual entries must have at least a name or a key. The name is used to
+create accessor and modifier functions. It's also used as the key in the config
+file. If \<key\> is given, but not \<name\>, the name is constructed by removing
+all spaces from \<key\>.
+
+An entry must also have a type. The list of allowable types is
+specified in the DTD and loosely follows the list of types supported
+by the TQt::Variant with exception of the clearly binary types
+(e.g. Pixmap, Image...) which are not supported. Besides those basic
+type the following special types are supported:
+
+- Path  This is a string that is specially treated as a file-path. 
+  In particular paths in the home directory are prefixed with $HOME in
+  when being stored in the configuration file.
+  
+- Enum  This indicates an enumeration. The possible enum values should
+  be provided via the \<choices\> tag. Enum values are accessed as integers
+  by the application but stored as string in the configuration file. This
+  makes it possible to add more values at a later date without breaking
+  compatibility.
+
+- IntList  This indicates a list of integers. This information is provided
+  to the application as an Array of Integers. Useful for storing TQt::Splitter
+  geometries.
+
+An entry can optionally have a default value which is used as default when
+the value isn't specified in any config file. Default values are interpreted
+as literal constant values. If a default value needs to be computed
+or if it needs to be obtained from a function call, the \<default\> tag
+should contain the code="true" attribute. The contents of the \<default\>
+tag is then considered to be a ruby expression.
+
+Additional code for computing default values can be provided via
+the \<code\> tag. The contents of the \<code\> tag is inserted as-is. A
+typical use for this is to compute a common default value which can
+then be referenced by multiple entries that follow.
+
+<h2>Code generation options</h2>
+
+The options for generating the Ruby sources are read from the file with the
+extension .kcfgc. To generate a class add the corresponding kcfgc file to the
+SOURCES line in the Makefile.am.
+
+The following options are read from the kcfgc file:
+
+<table>
+<tr>
+  <td><b><i>Name</i></b></td>
+  <td><b><i>Type</i></b></td>
+  <td><b><i>Default</i></b></td>
+  <td><b><i>Description</i></b></td>
+</tr>

+  <td>Names of files to be included in the header of the generated class</td>
+</tr>
+<tr>
+  <td><b>Mutators</b></td>
+  <td>true, false or a comma seperated list of options</td>
+  <td>-</td>
+  <td>If true, mutator functions for all configuration options are generated.
+      If false, no mutator functions are generated. If a list is provided,
+      mutator functions are generated for the options that are listed.</td>

+  <td>bool</td>

+</tr>
+<tr>
+  <td><b>GlobalEnums</b></td>
+  <td>bool</td>
+  <td>false</td>
+  <td>If set to true all choices of Enum items will be created in the global
+  scope of the generated class. If set to false, each Enum item will get an own
+  namespace for its choices.</td>
+</tr>
+</table>

+
+<h2>Advanced options</h2>
+
+There are several possibilities to parameterize entries.
+
+- Parameterized entries
+
+An entry can be parameterized using a fixed range parameter specified with
+the \<parameter\> tag. Such parameter can either be an Enum or an int. An Enum
+parameter should specify the possible enumeration values with the \<choices\>
+tag. An int parameter should specify its maximum value. Its minimum value
+is always 0.
+
+A parameterized entry is expanded to a number of entries, one for each
+value in the parameter range. The name and key should contain a reference
+to the parameter in the form of $(parameter-name). When expanding the entries
+the $(parameter-name) part is replaced with the value of the parameter.
+In the case of an Enum parameter it is replaced with the name of the
+enumuration value. In the case of an int parameter it is replaced with
+the numeric value of the parameter.
+
+Parameterized entries all share the same default value unless different
+default values have been specified for specific parameter values.
+This can be done with the param= attribute of the \<default\>. When a
+param attribute is specified the default value only applies to that
+particular parameter value.
+
+Example 1:
+\verbatim
+  <entry name="Color$(ColorIndex)" type="Color" key="color_$(ColorIndex)">
+    <parameter name="ColorIndex" type="Int" max="3"/>
+    <default param="0">#ff0000</default>
+    <default param="1">#00ff00</default>
+    <default param="2">#0000ff</default>
+    <default param="3">#ffff00</default>
+  </entry>
+\endverbatim
+
+The above describes 4 color configuration entries with the following defaults:
+
+color_0=#ff0000
+color_1=#00ff00
+color_2=#0000ff
+color_3=#ffff00
+
+The configuration options will be accessible to the application via
+a color(colorIndex) and a 
+setColor(colorIndex, v) method.
+
+Example 2:
+\verbatim
+  <entry name="Sound$(SoundEvent)" type="String" key="sound_$(SoundEvent)">
+    <parameter name="SoundEvent" type="Enum">
+      <values>
+        <value>Explosion</value>
+        <value>Crash</value>
+        <value>Missile</value>
+      </values>
+    </parameter>
+    <default param="Explosion">boom.wav</default>
+    <default param="Crash">crash.wav</default>
+    <default param="Missile">missile.wav</default>
+  </entry>
+\endverbatim
+
+The above describes 3 string configuration entries with the following defaults:
+
+sound_Explosion=boom.wav
+sound_Crash=crash.wav
+sound_Missile=missile.wav
+
+The configuration options will be accessible to the application via
+a sound(soundEvent) and a 
+setSound(soundEvent, v) method.
