/**
 * This java file is intended to be used with the bash script "gtk_version_tests.sh" normally found in:
 * ~/git/eclipse.platform.swt/tests/org.eclipse.swt.tests/
 *
 * It is intended to run SWT JUnit tests on multiple GTK versions in batch. Ex GTK2.24, GTK3.14 GTK3.16 etc..
 * This is convenient for patch submissions/reviews.
 *
 * For more details, see: https://wiki.eclipse.org/SWT/Devel/Gtk/JUnitTests#Running_jUnit_tests_across_multiple_versions_of_GTK
