+<p>
+  Building Tomcat involves downloading a number of libraries that it depends on.

+
+<p>
+  By default the build is configured to download the dependencies into the
+  <code>${user.home}/tomcat-build-libs</code> directory. You can change this
+  (see below) but it must be an absolute path.
+</p>
+
+<p>
+  The build is controlled by creating a
+  <code>${tomcat.source}/build.properties</code> file. It can be used to
+  redefine any property that is present in <code>build.properties.default</code>
+  and <code>build.xml</code> files. The <code>build.properties</code> file
+  does not exist by default. You have to create it.
+</p>
+
+<p>
+  The download area is defined by property <code>base.path</code>. For example:
+</p>
+
+<div class="codeBox"><pre><code># ----- Default Base Path for Dependent Packages -----
+# Replace this path with the directory path where
+# dependencies binaries should be downloaded.

+
+<p>

+
+<div class="codeBox"><pre><code>base.path=${user.dir}/../libraries-tomcat7.0</code></pre></div>

-The build can be controlled by creating a ${tomcat.source}/build.properties

-<code><br>
-    # ----- Proxy setup -----<br>

+Once the build has completed successfully, a usable Tomcat installation will have been
+produced in the <code>${tomcat.source}/output/build</code> directory, and can be started

-Use Windows-&gt;Preferences and then Java-&gt;Build Path-&gt;Classpath
-Variables to add two new Classpath variables:
+<b>WARNING:</b> Do not forget to create and configure

-<table border="1">
- <tr><td>TOMCAT_LIBS_BASE</td><td>the base path where the binary dependencies have been downloaded</td></tr>

+Sample Eclipse project files and launch targets are provided in the
+<code>res/ide-support/eclipse</code> directory of the source tree.
+The instructions below will automatically copy these into the required locations.
+</p>
+<p>
+Two Ant targets are provided as a convenience. The first one, named
+<em>ide-eclipse</em>, downloads all binary dependencies and configures
+Eclipse project in the root of the source tree. The created Eclipse project
+targets a Java 6 JDK and skips WebSocket classes that cannot be compiled with
+Java 6.
+</p>
+
+<p>
+The second target, named <em>ide-eclipse-websocket</em>, creates directory
+<code>../tomcat-7.0.x-java7</code> and configures the second Eclipse project
+there. This project targets a Java 7 JDK. This project does not have its own
+source tree, but accesses a subset of the source tree of the first project,
+compiling all WebSocket classes that were skipped.
+</p>
+
+<p>
+<code>cd ${tomcat.source}</code><br>
+<code>ant ide-eclipse</code><br>
+<code>ant ide-eclipse-websocket</code>
+</p>
+
+<p>
+Start Eclipse and create a new Workspace.
+</p>
+
+<p>
+Open the <em>Preferences</em> dialog and then select <em>Java-&gt;Build Path-&gt;Classpath
+Variables</em> to add two new <em>Classpath Variables</em>:
+</p>
+
+
+<table class="defaultTable">
+ <tr><td>TOMCAT_LIBS_BASE</td><td>The same location as the <code>base.path</code>
+  setting in <code>build.properties</code>, where the binary dependencies have been downloaded</td></tr>
+ <tr><td>ANT_HOME</td><td>the base path of Ant 1.8.2 or later</td></tr>
 </table>
+
+<p>
+In the <em>Preferences</em> dialog go to <em>Java-&gt;Installed JREs</em>
+and add JDK 6 and JDK 7 there. Close the dialog.
 </p>
 
 <p>
-There are two files in the root directory, <code>eclipse.classpath</code> and
-<code>eclipse.project</code>. Create their copies with new names,
-<code>.classpath</code> and <code>.project</code> respectively.
+Use <em>File-&gt;Import</em> command from menu and choose <em>Existing Projects into Workspace</em>.
+From there choose the root directory of the Tomcat source tree (<code>${tomcat.source}</code>)
+and import the project located there. Import the second project as well,
+if you have created it (<code>../tomcat-7.0.x-java7</code>).
 </p>
 
 <p>
-Use File-&gt;Import and chose "Existing Projects into Workspace".
-From there import the root directory where you have checked out tomcat.
+<code>start-tomcat</code> and <code>stop-tomcat</code> launch configurations are provided in
+<code>res/ide-support/eclipse</code> and will be available in the <em>Run-&gt;Run Configurations</em>
+dialog. Use these to start and stop Tomcat from Eclipse.
+If you want to configure these yourself (or are using a different IDE)
+then use <code>org.apache.catalina.startup.Bootstrap</code> as the main class,
+<code>start</code>/<code>stop</code> etc. as program arguments, and specify <code>-Dcatalina.home=...</code>
+(with the name of your build directory) as VM arguments.
 </p>
 
 <p>
-Eclipse .project and .classpath files provided in the root directory of
-tomcat repository should allow Eclipse to find all source trees and jars, and
-hopefully compile without problems. <b>Note</b> that these
-files assume you are using Eclipse with a 5.0 or later JDK.
+Tweaking a few formatting preferences will make it much easier to keep consistent with Tomcat
+coding conventions (and have your contributions accepted):
 </p>
 
+<table class="defaultTable">
+  <tr><td>Java -&gt; Code Style -&gt; Formatter -&gt; Edit...</td>
+  <td>Tab policy: Spaces only<br>Tab and Indentation size: 4</td></tr>
+  <tr><td>General -&gt; Editors -&gt; Text Editors</td>
+  <td>Displayed tab width: 2<br>Insert spaces for tabs<br>Show whitespace characters (optional)</td></tr>
+  <tr><td>XML -&gt; XML Files -&gt; Editor</td><td>Indent using spaces<br>Indentation size: 2</td></tr>
+  <tr><td>Ant -&gt; Editor -&gt; Formatter</td><td>Tab size: 2<br>Use tab character instead of spaces: unchecked</td></tr>
+</table>
+
 <p>
-To run Tomcat without a special IDE plug-in, you can simply use Run-&gt;Run...
-enter "org.apache.catalina.startup.Catalina" as the main class,
-"start" as program arguments, and
-"-Dcatalina.home=..." (with the name of your build directory) 
-as VM arguments.
+The recommended configuration of Compiler Warnings is documented in
+<code>res/ide-support/eclipse/java-compiler-errors-warnings.txt</code> file.
