This is just a small tool that takes an image and represents it as a circuit board-ish svg file.
Use the gradle wrapper by running
./gradlew build
to build the tool. Afterwards, run the tool via
java -jar build/libs/technicalizer.jar
and you'll get an error message about how you need to specify input and output files. Provide these as two command line parameters to the tool, i.e.
java -jar build/libs/technicalizer.jar input.png output.svg
and you're done.
