-This POM provides a parent from which SciJava-based projects can declare their build configurations. It ensures that projects all use a compatible build environment, as well as versions of dependencies and plugins. Projects extending this POM inherit the unified SciJava [Bill of Materials](http://imagej.net/BOM): component versions which have been tested to work together.
