After you have declared the options that the
Zend_Console_Getopt object should recognize, and supply
arguments from the command-line or an array, you can
query the object to find out which options were specified by a user in
a given command-line invocation of your program. The class implements
magic methods so you can query for options by name.
The parsing of the data is deferred until the first query you make
against the Zend_Console_Getopt object to find out if an
option was given, the object performs its parsing. This allows you to
use several method calls to configure the options, arguments, help
strings, and configuration options before parsing takes place.
