-   Generators are functions that create file formats from nix data structures,
-   e. g. for configuration files. There are generators available for:
-   <literal>INI</literal>, <literal>JSON</literal> and <literal>YAML</literal>
-  </para>
-
-  <para>
-   All generators follow a similar call interface: <code>generatorName
-   configFunctions data</code>, where <literal>configFunctions</literal> is an
-   attrset of user-defined functions that format nested parts of the content.
-   They each have common defaults, so often they do not need to be set
-   manually. An example is <code>mkSectionName ? (name: libStr.escape [ "[" "]"
-   ] name)</code> from the <literal>INI</literal> generator. It receives the
-   name of a section and sanitizes it. The default
-   <literal>mkSectionName</literal> escapes <literal>[</literal> and
-   <literal>]</literal> with a backslash.
-  </para>
-
-  <para>
-   Generators can be fine-tuned to produce exactly the file format required by
-   your application/service. One example is an INI-file format which uses
-   <literal>: </literal> as separator, the strings
-   <literal>"yes"</literal>/<literal>"no"</literal> as boolean values and
-   requires all string values to be quoted:

-let
-  customToINI = generators.toINI {
-    # specifies how to format a key/value pair
-    mkKeyValue = generators.mkKeyValueDefault {
-      # specifies the generated string for a subset of nix values
-      mkValueString = v:
-             if v == true then ''"yes"''
-        else if v == false then ''"no"''
-        else if isString v then ''"${v}"''
-        # and delegats all other values to the default generator
-        else generators.mkValueStringDefault {} v;
-    } ":";
-  };
-
-# the INI file can now be given as plain old nix values
-in customToINI {
-  main = {
-    pushinfo = true;
-    autopush = false;
-    host = "localhost";
-    port = 42;
-  };
-  mergetool = {
-    merge = "diff3";
-  };

-  <para>
-   This will produce the following INI file as nix string:
-  </para>
-
-<programlisting>
-[main]
-autopush:"no"
-host:"localhost"
-port:42
-pushinfo:"yes"
-str\:ange:"very::strange"

-[mergetool]
-merge:"diff3"

-  <note>
-   <para>
-    Nix store paths can be converted to strings by enclosing a derivation
-    attribute like so: <code>"${drv}"</code>.
-   </para>

-   Detailed documentation for each generator can be found in
-   <literal>lib/generators.nix</literal>.
