-SLEEF has a tool for measuring and plotting execution time of each function in
-the library. It consists of an executable for measurements, a makefile for
-driving measurement and plotting, and a couple of scripts.
-
-In order to start a measurement, you need to first build the executable for
-measurement. CMake builds the executable along with the library. Please refer
-to [compiling and installing the library](../1-user-guide) for this.
-
-Then, change directory to `sleef/src/libm-benchmarks/`. You also need to set
-the build directory to `BUILDDIR` environment variable. You also need Java
-runtime environment.
-
-```sh
-export BUILDDIR=$PATH:`pwd`/../../build
-```
-
-Type "make measure". After compiling the tools, it will prompt a label for
-measurement. After you input a label, measurement begins. After a measurement
-finishes, you can repeat measurements under different configurations. If you
-want to measure on a different computer, please copy the entire directory on to
-that computer and continue measurements. If you have Intel Compiler installed
-on your computer, you can type "make measureSVML" to measure the computation
-time of SVML functions.
-
-```sh
-make measure
-./measure.sh benchsleef
-       ...
-  Enter label of measurement(e.g. My desktop PC) : Skylake
-  Measurement in progress. This may take several minutes.
-  Sleef_sind2_u10
-  Sleef_cosd2_u10
-  Sleef_tand2_u10
-  Sleef_sincosd2_u10
-       ...
-  Sleef_atanf8_u10
-  Sleef_atan2f8_u10
-  Sleef_atanf8_u35
-  Sleef_atan2f8_u35
-
-  Now, you can plot the results of measurement by 'make plot'.
-  You can do another measurement by 'make measure'.
-  You can start over by 'make restart'.
-```
-
-Then type `make plot` to generate graphs. 
-```sh
-make plot
-  javac ProcessData.java
-  java ProcessData *dptrig*.out
-  gnuplot script.out
-  mv output.png trigdp.png
-  java ProcessData *dpnontrig*.out
-  gnuplot script.out
-  mv output.png nontrigdp.png
-  java ProcessData *sptrig*.out
-  gnuplot script.out
-  mv output.png trigsp.png
-  java ProcessData *spnontrig*.out
-  gnuplot script.out
-  mv output.png nontrigsp.png
-```
-
-You need to have JDK and gnuplot installed on your computer.
-Install these with:
-```sh
-sudo apt install openjdk-19-jdk-headless
-```
-and
-```sh
-sudo apt install gnuplot
-```
-
-Four graphs are generated : trigdp.png, nontrigdp.png, trigsp.png
-and nontrigsp.png. Please see our [benchmark results](../5-performance/) for
-an example of generated graphs by this tool.
