Examples of jimm.util.Getopts

jimm.util.Getopts
Getopts is similar to the UN*X getopt() system call. It parses an array of Strings (usually the command line), looking for specified option flags and values.
An instance of Getopts parses the whole args list at once, and stores the option flags and values that it finds. @author Jim Menard,jimm@io.com

 * @param args command line array; each element is assumed to be a report
 * file name.
