-Micro version
-============================
-
-The runtime and generated code for MICRO_RUNTIME is smaller
-because it does not include support for the descriptor,
-reflection or extensions. Also, not currently supported
-are packed repeated elements nor testing of java_multiple_files.
-
-To create a jar file for the runtime and run tests invoke
-"mvn package -P micro" from the <protobuf-root>/java
-directory. The generated jar file is
-<protobuf-root>java/target/protobuf-java-2.2.0-micro.jar.
-
-If you wish to compile the MICRO_RUTIME your self, place
-the 7 files below, in <root>/com/google/protobuf and
-create a jar file for use with your code and the generated
-code:
-
-ByteStringMicro.java
-CodedInputStreamMicro.java
-CodedOutputStreamMicro.java
-InvalidProtocolBufferException.java
-MessageMicro.java
-StringUtf8Micro.java
-WireFormatMicro.java
-
-If you wish to change on the code generator it is located
-in /src/google/protobuf/compiler/javamicro.
-
-To generate code for the MICRO_RUNTIME invoke protoc with
---javamicro_out command line parameter. javamciro_out takes
-a series of optional sub-parameters separated by comma's
-and a final parameter, with a colon separator, which defines
-the source directory. Sub-paraemeters begin with a name
-followed by an equal and if that sub-parameter has multiple
-parameters they are seperated by "|". The command line options
-are:
-
-opt                  -> speed or space
-java_use_vector      -> true or false
-java_package         -> <file-name>|<package-name>
-java_outer_classname -> <file-name>|<package-name>
-
-opt:
-  This change the code generation to optimize for speed,
-  opt=speed, or space, opt=space. When opt=speed this
-  changes the code generation for strings to use
-  StringUtf8Micro which eliminates multiple conversions
-  of the string to utf8. The default value is opt=space.
-
-java_use_vector:
-  Is a boolean flag either java_use_vector=true or
-  java_use_vector=false. When java_use_vector=true the
-  code generated for repeated elements uses
-  java.util.Vector and when java_use_vector=false the
-  java.util.ArrayList<> is used. When java.util.Vector
-  is used the code must be compiled with Java 1.3 and
-  when ArrayList is used Java 1.5 or above must be used.
-  The using javac the source parameter maybe used to
-  control the version of the srouce: "javac -source 1.3".
-  You can also change the <source> xml element for the
-  maven-compiler-plugin. Below is for 1.5 sources:
-
-      <plugin>
-        <artifactId>maven-compiler-plugin</artifactId>
-        <configuration>
-          <source>1.5</source>
-          <target>1.5</target>
-        </configuration>
-      </plugin>
-
-  When compiling for 1.5 java_use_vector=false or not
-  present where the default value is false.
-
-  And below would be for 1.3 sources note when changing
-  to 1.3 you must also set java_use_vector=true:
-
-      <plugin>
-        <artifactId>maven-compiler-plugin</artifactId>
-        <configuration>
-          <source>1.3</source>
-          <target>1.5</target>
-        </configuration>
-      </plugin>
-
-java_package:
-  The allows setting/overriding the java_package option
-  and associates allows a package name for a file to
-  be specified on the command line. Overriding any
-  "option java_package xxxx" in the file. The default
-  if not present is to use the value from the package
-  statment or "option java_package xxxx" in the file.
-
-java_outer_classname:
-  This allows the setting/overriding of the outer
-  class name option and associates a class name
-  to a file. An outer class name is required and
-  must be specified if there are multiple messages
-  in a single proto file either in the proto source
-  file or on the command line. If not present the
-  no outer class name will be used.
-
-Below are a series of examples for clarification of the
-various javamicro_out parameters using
-src/test/proto/simple-data.proto:
-
-package testprotobuf;
-
-message SimpleData {
-  optional fixed64 id = 1;
-  optional string description = 2;
-  optional bool ok = 3 [default = false];
-};
-
-
-Assuming you've only compiled and not installed protoc and
-your current working directory java/, then a simple
-command line to compile simple-data would be:
-
-../src/protoc --javamicro_out=. src/test/proto/simple-data.proto
-
-This will create testprotobuf/SimpleData.java
-
-The directory testprotobuf is created because on line 1
-of simple-data.proto is "package testprotobuf;". If you
-wanted a different package name you could use the
-java_package option command line sub-parameter:
-
-../src/protoc '--javamicro_out=java_package=src/test/proto/simple-data.proto|my_package:.' src/test/proto/simple-data.proto
-
-Here you see the new java_package sub-parameter which
-itself needs two parameters the file name and the
-package name, these are separated by "|". Now you'll
-find my_package/SimpleData.java.
-
-If you wanted to also change the optimization for
-speed you'd add opt=speed with the comma seperator
-as follows:
-
-../src/protoc '--javamicro_out=opt=speed,java_package=src/test/proto/simple-data.proto|my_package:.' src/test/proto/simple-data.proto
-
-Finally if you also wanted an outer class name you'd
-do the following:
-
-../src/protoc '--javamicro_out=opt=speed,java_package=src/test/proto/simple-data.proto|my_package,java_outer_classname=src/test/proto/simple-data.proto|OuterName:.' src/test/proto/simple-data.proto
-
-Now you'll find my_packate/OuterName.java.
-
-As mentioned java_package and java_outer_classname
-may also be specified in the file. In the example
-below we must define java_outer_classname because
-there are multiple messages in
-src/test/proto/two-messages.proto
-
-package testmicroruntime;
-
-option java_package = "com.example";
-option java_outer_classname = "TestMessages";
-
-message TestMessage1 {
-  required int32 id = 1;
-}
-
-message TestMessage2 {
-  required int32 id = 1;
-}
-
-This could be compiled using:
-
-../src/protoc --javamicro_out=. src/test/proto/two-message.proto
-
-With the result will be com/example/TestMessages.java
-

-/**
- * A Performance Timing class that can be used to estimate the amount of time a
- * sequence of code takes. The typical code sequence would be as follows:</p>
- * <code>
- PerfTimer pt = new PerfTimer();
- pt.calibrate();
- pt.timeEachAutomatically(new Runnable() = {
-    public void run() {
-        // Add code to time
-    }
- });
- System.out.printf("time per loop=" + pt);
-
- * The calibrate method determines the overhead of timing the run() method and
- * the number of times to call the run() method to have approximately 1% precision
- * for timing. The method pt.stats() method will return a string containing some
- * statistics tpl, il, ol, min, max, mean, median, stddev and total.
- *
- * tpl    ::= Timer per loop
- * min    ::= minimum time one call to run() took
- * stddev ::= Standard deviation of the collected times
- * mean   ::= the average time to call run()
- * median ::= 1/2 the times were > than this time and 1/2 were less.
- * total  ::= Sum of the times collected.
- * il     ::= innerLoops; the number of times run() between each call to start/stop
- * ol     ::= outerLoops, the number of times start/stop was called
- *
- * You can also use start/stop/restart to do simple timing:
- *
- * pt.start();
- * a += 1;
- * pt.stop();
- * pt.log("time=" + pt);
- * pt.restart();
- * doSomething();
- * pt.stop();
- * System.out.printf("time=" + pt);
- * </code>
