-
-## Getting Sources
-### macOS, Linux
-```
-git config --global core.autocrlf input
-git clone git@github.com:JetBrains/JetBrainsRuntime.git
-```
-
-### Windows
-<a name="sources-windows"></a>
-```
-git config --global core.autocrlf false
-git clone git@github.com:JetBrains/JetBrainsRuntime.git
-```
-
-## Configuring the Build Environment
-Here are quick per-platform instructions for those who can't wait to get started. 
-Please refer to [OpenJDK build docs](https://openjdk.java.net/groups/build/doc/building.html) for in-depth
-coverage of all the details.
-
-> **_TIP:_**  To get a preliminary report of what's missing, run `./configure` and check its output. 
-> It would usually have a meaningful advice on how to solve the problem.
-
-### Linux (Docker)
-Create a container:
-```
-$ cd jb/project/docker
-$ docker build .
-...
-Successfully built 942ea9900054
-```
-Run these commands in the new container:
-```
-$ docker run -v `pwd`../../../../:/JetBrainsRuntime -it 942ea9900054
-# cd /JetBrainsRuntime
-# git checkout master17
-# sh ./configure
-# make images CONF=linux-x86_64-normal-server-release
-```
-
-### Ubuntu Linux
-Install the necessary tools, libraries, and headers with:
-```
-$ sudo apt-get install autoconf make build-essential libx11-dev libxext-dev libxrender-dev libxtst-dev \
-       libxt-dev libxrandr-dev libcups2-dev libfontconfig1-dev libasound2-dev \
-       java-16-amazon-corretto-jdk
-```
-Then run the following:
-```
-$ cd JetBrainsRuntime
-$ git checkout master17
-$ sh ./configure
-$ make images
-```
-This will build the release configuration under `./build/linux-x86_64-server-release/`.
-
-### Windows
-<a name="build-windows"></a>
-Install the following:
-* [Cygwin x64](http://www.cygwin.com/).
-  Required packages: `autoconf`, `binutils`, `cpio`, `diffutils`, `file`, `gawk`, `gcc-core`, `make`, `m4`, `unzip`, `zip`.  
-  Install those together with Cygwin.
-* [Visual Studio compiler toolset](https://visualstudio.microsoft.com/downloads/).
-  Install with the desktop development kit, which includes Windows SDK and compilers.
-  Visual Studio 2019 is supported by default.
-* Java 16 (for instance, from [AdoptOpenJDK](https://adoptopenjdk.net/installation.html?variant=openjdk16&jvmVariant=hotspot#)).
-  If you have problems while configuring, read [Java tips on Cygwin](http://horstmann.com/articles/cygwin-tips.html).
-
-From the command line: 
-```
-"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" amd64
-"c:\Program_Files\cygwin64\bin\mintty.exe" /bin/bash -l
-```
-The first command sets up environment variables, the second starts a Cygwin shell with the proper environment.  
-
-In the Cygwin shell: 
-```
-$ cd JetBrainsRuntime
-$ git checkout master17
-$ bash configure --with-toolchain-version=2019
-$ make images
-```
-This will build the release configuration under `./build/windows-x86_64-server-release/`.
-
-### macOS
-Install the following:
-* Xcode command line developer tools and `autoconf` via [Homebrew](getDpiInfo).
-* Java 16 (for instance, from [AdoptOpenJDK](https://adoptopenjdk.net/installation.html?variant=openjdk16&jvmVariant=hotspot#)).
-
-From the command line:
-```
-$ cd JetBrainsRuntime
-$ git checkout master17
-$ sh ./configure
-$ make images
-```
-This will build the release configuration under `./build/macosx-x86_64-server-release/`.

- * The class reads J2DBench scores and reports them into output stream in format applicable for TeamCity charts.
- * The directory, where J2DBench result files placed, is specified via command line parameter like follows:
- * <p>
- * <code>-basexml | -b <xml file path></code>
- * </p>
- * This directory must contain one file with pattern <code>*{openjdk}*.{res}</code> which is considered as a container
- * of reference scores and several <code>*{jbsdk}*.{res}</code>.
- * <p>
- * <p> Names of these files have several mandatory fields separated by <code>"_"</code> and look like
- * <code>osName_jdkName_renderName_*.res</code>
- * </p>
- * <p>
- * If any of score is less than corresponding reference value by 5% then exit code <code>1</code> is returned otherwise
- * exit code <code>0</code> is returned.
- * <p>
- * Standard output will contain scores in format required for TeamCity charts.

------------------------------------------------------------------------
-Introduction
------------------------------------------------------------------------
-
-RenderPerfTest is a set of on-screen rendering microbenchmarks  to
-analyze the  performance of Java2D graphical primitives rendering
-
------------------------------------------------------------------------
-How To Compile
------------------------------------------------------------------------
-
-#> cd RenderPerfTest
-
-The benchmark can be compiled by using either ant:
-
-#> ant
-
-or gnumake (assuming there's 'javac' in the path):
-
-#> gnumake
-
-The jar files will be generated into RenderPerfTest/dist directory.
-
------------------------------------------------------------------------
-How To Run RenderPerfTest
------------------------------------------------------------------------
-Run all tests
-#> ant run
-  or
-#> java -jar dist/RenderPerfTest.jar
-
-Run particular test cases
-
-#> java -jar dist/RenderPerfTest.jar testWhiteTextBubblesGray ...
