Make sure, that you installed OpenJDK Java and GNU Make or compatibles. The following command will download the common-compress package and build the command line tools:
make allThe following command will test, that the command-line tools work:
make testThe following command will remove build and test output files:
make cleanThe following command will remove all files created by the Makefile, including the downloaded commons-compress package:
make distcleanIn lieu of a formal styleguide, take care to maintain the existing coding style.
