rosprolog is a simple wrapper around swi-prolog that uses an additional user-init file.
Two new predicates are added in this file:
 * use_ros_module( <ros-package-name>, '<prolog-file-path>' )
   Load a prolog module from $(rospack find <ros-package-name>)/prolog/<prolog-file-path>.
 * rospack_package_path( Package, Path )
   Get the absolute path of a package.

To run rosprolog, use:
rosrun rosprolog rosprolog

To start a prolog package within rosprolog (incl. calling its init.pl file and all init.pl of referenced packages), use:
rosrun rosprolog rosprolog <pkgname>
