The UnboundID LDAP SDK for Java is a fast, comprehensive, and easy-to-use
Java API for communicating with LDAP directory servers and performing
related tasks like reading and writing LDIF, encoding and decoding data
using base64 and ASN.1 BER, and performing secure communication. This
package contains the Standard Edition of the LDAP SDK, which is a
complete, general-purpose library for communicating with LDAPv3 directory
servers.

/**
* Creates a new argument that is intended to represent Boolean states based on
* whether it was present in the provided set of command-line arguments.
* Boolean arguments never have values, since the argument identifier itself is
* sufficient to indicate presence. If the argument is present in the set of
* provided command-line arguments, then it will be assumed to have a value of
* {@code true}. If the argument is not present, then it will be assumed to
* have a value of {@code false}.
*
* Note that it may be beneficial in some cases to allow multiple occurrences of
* the same Boolean argument if that has special meaning (e.g., if "-v" is used
* to enable verbose output, then perhaps "-v -v" would be even more verbose).
