/*
 * Release checklist
 * - Test with Hibernate
 * - Run FindBugs
 * - ant jarClient, check jar file size
 *
 * - Compile with JDK 1.4, 1.5 and 1.6:
 *   set path=C:\Programme\Java\jdk1.6.0\bin;%PATH%
 *   set JAVA_HOME=C:\Programme\Java\jdk1.6.0
 *   set path=C:\Program Files\Java\jdk1.6.0_01\bin;%PATH%
 *   set JAVA_HOME=C:\Program Files\Java\jdk1.6.0_01
 *   ant compile
 *   set classpath=
 *   ant javadoc
 *   ant javadocImpl (to find missing javadocs)
 *   ant codeswitchJdk14
 *   ant javadocImpl
 *
 * - Change version and build number in
 *     Constants.java
 *     ant-build.properties
 *     build.html
 *     mainWeb.html
 *     download.html
 * - Maybe increase TCP_DRIVER_VERSION (but clients must be backwards compatible!)
 * - Check code coverage
 * - No "  Message.get" (must be "throw Message.get")
 * - No TODO in the docs, remove @~ in .utf8.txt files
 * - Run regression test with JDK 1.4 and 1.5
 *
 * - Change version(s) in performance.html; use latest versions of other databases
 * - Run 'ant benchmark' (with JDK 1.4 currently)
 * - Copy the benchmark results and update the performance page and diagram
 *
 * - Documentation: if there are new files, add them to MergeDocs
 * - Documentation: check if all Javadoc files are in the index
 * - ant docs
 * - PDF
 *      - footer
 *      - front page
 *      - orphan control
 *      - check images
 *      - table of contents
 * - Switch off auto-build
 * - ant all
 * - Make sure FullTextLucene is included in h2.jar
 * - Copy the pdf file to h2/docs
 * - Make sure the build files are removed
 * - ant zip
 * - Windows installer (nsis)
 * - Test Console
 * - Test all languages
 * - Test the windows service
 * - Scan for viruses
 * - ant mavenDeployCentral
