Comment #7 on issue 4 by taroleo: Plugin feature for utgb-shell
http://code.google.com/p/utgb/issues/detail?id=4
This feature is implemented since utgb 1.5.4.
Developers can now easily add commands without changing utgb-shell.
See the package org.utgenome.core.cui containing such commands. To import
another package, see UTGBShell's code.
