+The optional file `'$site_path'/etc/All-Projects/project.config` provides

+link:config-project-config.html[`project.config`] in the
+`All-Projects` repo. Unlike `gerrit.config`, this file contains project-type

+
+Most administrators will not need this file, and should instead make commits to
+`All-Projects` to modify global config. However, a separate file can be useful
+when managing multiple Gerrit servers, since pushing changes to defaults using
+Puppet or a similar tool can be easier than scripting git updates to
+`All-Projects`.
+
+The contents of the file are loaded each time the `All-Projects` project is
+reloaded. Updating the file requires either evicting the project cache or
+restarting the server.
+
+Caveats:
+
+* The path from which the file is read corresponds to the name of the repo,
+  which is link:#gerrit.allProjects[configurable].
+* Although the file lives in a directory that shares a name with a repository,
+  this directory is not a Git repository.
+* Only the file `project.config` is read from this directory to provide
+  defaults; any other files in this directory, such as `rules.pl`, are ignored.
+  (This behavior may change in the future.)
+* Group names listed in the access config in this file are resolved to UUIDs
+  using the `groups` file in the repository, not in the config directory. As a
+  result, setting ACLs in this file is not recommended.

-=== Running GWT Debug Mode
-
-The `gerrit_gwt_debug` launch configuration uses GWT's
-link:http://www.gwtproject.org/articles/superdevmode.html[Super Dev Mode].
-
-* Make a local copy of the `gerrit_gwt_debug` configuration, using the
-process described for `gerrit_daemon` above.
-* Launch the local copy of `gerrit_gwt_debug` from the Eclipse debug menu.
-* If debugging GWT for the first time:
-
-** Open the link:http://localhost:9876/[codeserver URL] and add the `Dev Mode On`
-and `Dev Mode Off` bookmarklet to your bookmark bar.
-
-** Activate the source maps feature in your browser. Refer to the
-link:https://developer.chrome.com/devtools/docs/javascript-debugging#source-maps[
-Chrome] and
-link:https://developer.mozilla.org/en-US/docs/Tools/Debugger#Use_a_source_map[
-Firefox] developer documentation.
-
-* Load the link:http://localhost:8080[Gerrit page].
-* Open the source tab in developer tools.
-* Click the `Dev Mode On` bookmark to incrementally recompile changed files.
-* Select the `gerrit_ui` module to compile (the `Compile` button can also be used
-as a bookmarklet).
-* In the developer tools source tab, open a file and set a breakpoint.
-* Navigate to the UI and confirm that the breakpoint is hit.
-* To end the debugging session, click the `Dev Mode Off` bookmark.
-
-.After changing the client side code:
-
-* Hitting `F5` in the browser only reloads the last compile output, without
-recompiling.
-* To reflect your changes in the debug session, click `Dev Mode On` then `Compile`.

-=== Running GWT Debug Mode for Gerrit plugins
-
-A Gerrit plugin can expose GWT module and its implementation can be inspected
-in the SDM debug session.
-
-`codeserver` needs two additional inputs to expose the plugin module in the SDM
-debug session: the module name and the source folder location. For example the
-module name and source folder of `cookbook-plugin` should be added in the local
-copy of the `gerrit_gwt_debug` configuration:
-
-----
-  com.googlesource.gerrit.plugins.cookbook.HelloForm \
-  -src ${resource_loc:/gerrit}/plugins/cookbook-plugin/src/main/java \
-  -- --console-log [...]

-
-After doing that, both the Gerrit core and plugin GWT modules can be activated
-during SDM (debug session)[http://imgur.com/HFXZ5No].

+=== Calling Command Options ===
+
+Within an OptionHandler, during the processing of an option, plugins can
+provide and call extra parameters on the current command during parsing
+simulating as if they had been passed from the command line originally.
+
+To call additional parameters from within an option handler, instantiate
+the com.google.gerrit.util.cli.CmdLineParser.Parameters class with the
+existing parameters, and then call callParameters() with the additional
+parameters to be parsed. OptionHandlers may optionally pass this class to
+other methods which may then both parse/consume more parameters and call
+additional parameters.
+
+When calling command options not provided by your plugin, there is always
+a risk that the options may not exist, perhaps because the options being
+called are to be provided by another plugin, and said plugin is not
+currently installed. To protect againt this situation, it is possible to
+define an option as being dependent on other options using the
+@RequiresOptions() annotation. If the required options are not all not
+currently present, then the dependent option will not be available or
+visible in the help.
+
+The example below shows a plugin that adds a "--special" option (perhaps
+for use with the Query command) that calls (and requires) the
+"--format json" option.
+
+[source, java]
+----
+public class JsonOutputOptionHandler<T> extends OptionHandler<T> {
+  protected com.google.gerrit.util.cli.CmdLineParser.MyParser myParser;
+
+  public JsonOutputOptionHandler(CmdLineParser parser, OptionDef option, Setter<? super T> setter) {

+  }

-module name compiled into the plugin. The name of the GWT module
-can be explicitly set in the GWT module XML file by specifying

-
-By defining an link:config-gerrit.html#urlAlias[urlAlias] Gerrit

-Plugins may also programatically add URL aliases in the preferences of

-   * Helper method to retrieve the line number on the other side.
-   *
-   * <p>Given a line number on one side, performs a binary search in the lineMap to find the
-   * corresponding LineGap record.
-   *
-   * <p>A LineGap records gap information from the start of an actual gap up to the start of the
-   * next gap. In the following example, lineMapAtoB will have LineGap: {start: 1, end: -1, delta:
-   * 3} (end set to -1 to represent a dummy gap of length zero. The binary search only looks at
-   * start so setting it to -1 has no effect here.) lineMapBtoA will have LineGap: {start: 1, end:
-   * 3, delta: -3} These LineGaps control lines between 1 and 5.
-   *
-   * <p>The "delta" is computed as the number to add on our side to get the line number on the other
-   * side given a line after the actual gap, so the result will be (line + delta). All lines within
-   * the actual gap (1 to 3) are considered corresponding to the last line above the region on the
-   * other side, which is 0 in this case. For these lines, we do (end + delta).
-   *
-   * <p>For example, to get the line number on the left corresponding to 1 on the right
-   * (lineOnOther(REVISION, 1)), the method looks up in lineMapBtoA, finds the "delta" to be -3, and
-   * returns 3 + (-3) = 0 since 1 falls in the actual gap. On the other hand, the line corresponding
-   * to 5 on the right will be 5 + (-3) = 2, since 5 is in the region after the gap (but still
-   * controlled by the current LineGap).
-   *
-   * <p>PARENT REVISION 0 | 0 - | 1 \ \ - | 2 | Actual insertion gap | - | 3 / | Region controlled
-   * by one LineGap 1 | 4 <- delta = 4 - 1 = 3 | 2 | 5 / - | 6 ...

-/**
- * Class for grouping together callbacks and calling them in order.
- *
- * <p>Callbacks are added to the group with {@link #add(AsyncCallback)}, which returns a wrapped
- * callback suitable for passing to an asynchronous RPC call. The last callback must be added using
- * {@link #addFinal(AsyncCallback)} or {@link #done()} must be invoked.
- *
- * <p>The enclosing group buffers returned results and ensures that {@code onSuccess} is called
- * exactly once for each callback in the group, in the same order that callbacks were added. This
- * allows callers to, for example, use a {@link ScreenLoadCallback} as the last callback in the list
- * and only display the screen once all callbacks have succeeded.
- *
- * <p>In the event of a failure, the <em>first</em> caught exception is sent to <em>all</em>
- * callbacks' {@code onFailure} methods, in order; subsequent successes or failures are all ignored.
- * Note that this means {@code onFailure} may be called with an exception unrelated to the callback
- * processing it.
