+        docs                 Static documentation files to be copied to

+
+
+<!-- ==================== File and Directory Names ======================== -->
+
+
+<!--
+
+  These properties generally define file and directory names (or paths) that
+  affect where the build process stores its outputs.
+
+  app.name             Base name of this application, used to
+                       construct filenames and directories.
+                       Defaults to "myapp".
+
+  app.path             Context path to which this application should be
+                       deployed (defaults to "/" plus the value of the
+                       "app.name" property).
+
+  app.version          Version number of this iteration of the application.
+
+  build.home           The directory into which the "prepare" and
+                       "compile" targets will generate their output.
+                       Defaults to "build".
+
+  catalina.home        The directory in which you have installed
+                       a binary distribution of Tomcat.  This will
+                       be used by the "deploy" target.
+
+  dist.home            The name of the base directory in which
+                       distribution files are created.
+                       Defaults to "dist".
+
+  manager.password     The login password of a user that is assigned the
+                       "manager-script" role (so that he or she can execute
+                       commands via the "/manager" web application)
+
+  manager.url          The URL of the "/manager" web application on the
+                       Tomcat installation to which we will deploy web
+                       applications and web services.
+
+  manager.username     The login username of a user that is assigned the
+                       "manager-script" role (so that he or she can execute
+                       commands via the "/manager" web application)

+
+
+<!-- ==================== External Dependencies =========================== -->
+
+
+<!--
+
+  Use property values to define the locations of external JAR files on which
+  your application will depend.  In general, these values will be used for
+  two purposes:
+  * Inclusion on the classpath that is passed to the Javac compiler
+  * Being copied into the "/WEB-INF/lib" directory during execution
+    of the "deploy" target.
+
+  Because we will automatically include all of the Java classes that Tomcat
+  exposes to web applications, we will not need to explicitly list any of those
+  dependencies.  You only need to worry about external dependencies for JAR
+  files that you are going to include inside your "/WEB-INF/lib" directory.
+
+-->
+
+<!-- Dummy external dependency -->
+  <!--property name="vaadin.jar" value="/opt/vaadin/WebContent/vaadin-6.6.6.jar"/-->
+
+
+<!-- ==================== Compilation Classpath =========================== -->
+
+<!--
+
+  Rather than relying on the CLASSPATH environment variable, Ant includes
+  features that makes it easy to dynamically construct the classpath you
+  need for each compilation.  The example below constructs the compile
+  classpath to include the servlet.jar file, as well as the other components
+  that Tomcat makes available to web applications automatically, plus anything
+  that you explicitly added.
+
+-->
+
+  <path id="compile.classpath">
+
+    <!-- Include all JAR files that will be included in /WEB-INF/lib -->
+    <fileset dir="${web.home}/WEB-INF/lib">

+    <pathelement location="${vaadin.jar}"/>

+
+
+<!-- ================== Custom Ant Task Definitions ======================= -->
+
+
+<!--
+
+  These properties define custom tasks for the Ant build tool that interact
+  with the "/manager" web application installed with Tomcat.  Before they
+  can be successfully utilized, you must perform the following steps:
+
+  - Copy the file "lib/catalina-ant.jar" from your Tomcat
+    installation into the "lib" directory of your Ant installation.
+
+  - Create a "build.properties" file in your application's top-level
+    source directory (or your user login home directory) that defines
+    appropriate values for the "manager.password", "manager.url", and
+    "manager.username" properties described above.
+
+  For more information about the Manager web application, and the functionality
+  of these tasks, see <http://localhost:8080/tomcat-docs/manager-howto.html>.

+<!--  ==================== Compilation Control Options ==================== -->
+
+<!--
+
+  These properties control option settings on the Javac compiler when it
+  is invoked using the <javac> task.
+
+  compile.debug        Should compilation include the debug option?

+  environment is modified.  Note that property composition is allowed within
+  "build.properties" files as well as in the "build.xml" script.
+
+-->
+
+  <property file="build.properties"/>
+  <property file="${user.home}/build.properties"/>
+
+
+<!-- ==================== File and Directory Names ======================== -->
+
+
+<!--
+
+  These properties generally define file and directory names (or paths) that
+  affect where the build process stores its outputs.
+
+  app.name             Base name of this application, used to
+                       construct filenames and directories.
+                       Defaults to "myapp".
+
+  app.path             Context path to which this application should be
+                       deployed (defaults to "/" plus the value of the
+                       "app.name" property).
+
+  app.version          Version number of this iteration of the application.
+
+  build.home           The directory into which the "prepare" and
+                       "compile" targets will generate their output.
+                       Defaults to "build".
+
+  catalina.home        The directory in which you have installed
+                       a binary distribution of Tomcat 6.  This will
+                       be used by the "deploy" target.
+
+  dist.home            The name of the base directory in which
+                       distribution files are created.
+                       Defaults to "dist".
+
+  manager.password     The login password of a user that is assigned the
+                       "manager-script" role (so that he or she can execute
+                       commands via the "/manager" web application)
+
+  manager.url          The URL of the "/manager" web application on the
+                       Tomcat installation to which we will deploy web
+                       applications and web services.
+
+  manager.username     The login username of a user that is assigned the
+                       "manager-script" role (so that he or she can execute
+                       commands via the "/manager" web application)
+
+-->
+
+  <property name="app.name"      value="myapp"/>
+  <property name="app.path"      value="/${app.name}"/>
+  <property name="app.version"   value="0.1-dev"/>
+  <property name="build.home"    value="${basedir}/build"/>
+  <property name="catalina.home" value="../../../.."/> <!-- UPDATE THIS! -->
+  <property name="dist.home"     value="${basedir}/dist"/>
+  <property name="docs.home"     value="${basedir}/docs"/>
+  <property name="manager.url"   value="http://localhost:8080/manager/text"/>
+  <property name="src.home"      value="${basedir}/src"/>
+  <property name="web.home"      value="${basedir}/web"/>
+
+
+<!-- ==================== External Dependencies =========================== -->
+
+
+<!--
+
+  Use property values to define the locations of external JAR files on which
+  your application will depend.  In general, these values will be used for
+  two purposes:
+  * Inclusion on the classpath that is passed to the Javac compiler
+  * Being copied into the "/WEB-INF/lib" directory during execution
+    of the "deploy" target.
+
+  Because we will automatically include all of the Java classes that Tomcat 6
+  exposes to web applications, we will not need to explicitly list any of those
+  dependencies.  You only need to worry about external dependencies for JAR
+  files that you are going to include inside your "/WEB-INF/lib" directory.
+
+-->
+
+<!-- Dummy external dependency -->
+<!--
+  <property name="foo.jar"
+           value="/path/to/foo.jar"/>
+-->
+
+
+<!-- ==================== Compilation Classpath =========================== -->
+
+<!--
+
+  Rather than relying on the CLASSPATH environment variable, Ant includes
+  features that makes it easy to dynamically construct the classpath you
+  need for each compilation.  The example below constructs the compile
+  classpath to include the servlet.jar file, as well as the other components
+  that Tomcat makes available to web applications automatically, plus anything
+  that you explicitly added.
+
+-->
+
+  <path id="compile.classpath">
+
+    <!-- Include all JAR files that will be included in /WEB-INF/lib -->
+    <!-- *** CUSTOMIZE HERE AS REQUIRED BY YOUR APPLICATION *** -->
+<!--
+    <pathelement location="${foo.jar}"/>
+-->
+
+    <!-- Include all elements that Tomcat exposes to applications -->
+    <fileset dir="${catalina.home}/bin">
+      <include name="*.jar"/>
+    </fileset>
+    <pathelement location="${catalina.home}/lib"/>

+      <include name="*.jar"/>
+    </fileset>
+
+  </path>
+
+
+
+<!-- ================== Custom Ant Task Definitions ======================= -->
+
+
+<!--
+
+  These properties define custom tasks for the Ant build tool that interact
+  with the "/manager" web application installed with Tomcat 6.  Before they
+  can be successfully utilized, you must perform the following steps:
+
+  - Copy the file "lib/catalina-ant.jar" from your Tomcat 6
+    installation into the "lib" directory of your Ant installation.
+
+  - Create a "build.properties" file in your application's top-level
+    source directory (or your user login home directory) that defines
+    appropriate values for the "manager.password", "manager.url", and
+    "manager.username" properties described above.
+
+  For more information about the Manager web application, and the functionality
+  of these tasks, see <http://localhost:8080/tomcat-docs/manager-howto.html>.

+
+
+<!--  ==================== Compilation Control Options ==================== -->
+
+<!--
+
+  These properties control option settings on the Javac compiler when it
+  is invoked using the <javac> task.
+
+  compile.debug        Should compilation include the debug option?
+
+  compile.deprecation  Should compilation include the deprecation option?
+
+  compile.optimize     Should compilation include the optimize option?

+        This servlet produces GIF images that are dynamically generated
+        graphs, based on the input parameters included on the request.
+        It is generally mapped to a specific request URI like "/graph".

+    <!-- Define mappings that are used by the servlet container to
+         translate a particular request URI (context-relative) to a
+         particular servlet.  The examples below correspond to the
+         servlet descriptions above.  Thus, a request URI like:
+
+           http://localhost:8080/{contextpath}/graph
+
+         will be mapped to the "graph" servlet, while a request like:
+
+           http://localhost:8080/{contextpath}/saveCustomer.do
+
+         will be mapped to the "controller" servlet.
+
+         You may define any number of servlet mappings, including zero.
+         It is also legal to define more than one mapping for the same
+         servlet, if you wish to.
