Program name

For convenience the overall Java program is named Unravel. That name will be used extensively in this Online Help text. Note that this is not the name used for the main-class (UrvApp.class) or for the program's Java archive (urvall.jar). Also, the label UnravelJ (referring to Unravel developed using the Java programming language) will sometimes be used where there is a need to avoid conflict with the UnravelC label used for an earlier version of Unravel developed using the C++ programming language.
