/**
 * This class provides a command-line tool that can be used to run an instance
 * of the in-memory directory server.  Instances of the server may also be
 * created and controlled programmatically using the
 * {@link InMemoryDirectoryServer} class.
 * <BR><BR>
 * The following command-line arguments may be used with this class:
 * <UL>
 *   <LI>"-b {baseDN}" or "--baseDN {baseDN}" -- specifies a base DN to use for
 *       the server.  At least one base DN must be specified, and multiple
 *       base DNs may be provided as separate arguments.</LI>
 *   <LI>"-p {port}" or "--port {port}" -- specifies the port on which the
 *       server should listen for client connections.  If this is not provided,
 *       then a free port will be automatically chosen for use by the
 *       server.</LI>
 *   <LI>"-l {path}" or "--ldifFile {path}" -- specifies the path to an LDIF
 *       file to use to initially populate the server.  If this is not provided,
 *       then the server will initially be empty.  The LDIF file will not be
 *       updated as operations are processed in the server.</LI>
 *   <LI>"-D {bindDN}" or "--additionalBindDN {bindDN}" -- specifies an
 *       additional DN that can be used to authenticate to the server, even if
 *       there is no account for that user.  If this is provided, then the
 *       --additionalBindPassword argument must also be given.</LI>
 *   <LI>"-w {password}" or "--additionalBindPassword {password}" -- specifies
 *       the password that should be used when attempting to bind as the user
 *       specified with the "-additionalBindDN" argument.  If this is provided,
 *       then the --additionalBindDN argument must also be given.</LI>
 *   <LI>"-c {count}" or "--maxChangeLogEntries {count}" -- Indicates whether an
 *       LDAP changelog should be enabled, and if so how many changelog records
 *       should be maintained.  If this argument is not provided, or if it is
 *       provided with a value of zero, then no changelog will be
 *       maintained.</LI>
 *   <LI>"-A" or "--accessLogToStandardOut" -- indicates that access log
 *       information should be written to standard output.  This cannot be
 *       provided in conjunction with the "--accessLogFile" argument.  If
 *       neither argument is provided, then no access logging will be
 *       performed</LI>
 *   <LI>"-a {path}" or "--accessLogFile {path}" -- specifies the path to a file
 *       that should be used as a server access log.  This cannot be provided in
 *       conjunction with the "--accessLogToStandardOut" argument.  If neither
 *       argument is provided, then no access logging will be performed</LI>
 *   <LI>"---jsonAccessLogToStandardOut" -- indicates that JSON-formatted access
 *       log information should be written to standard output.  This cannot be
 *       provided in conjunction with the "--jsonAccessLogFile" argument.  If
 *       neither argument is provided, then no JSON-formatted access logging
 *       will be performed</LI>
 *   <LI>"--jsonAccessLogFile {path}" -- specifies the path to a file that
 *       should be used as a server access log with JSON-formatted messages.
 *       This cannot be provided in conjunction with the
 *       "--jsonAccessLogToStandardOut" argument.  If neither argument is
 *       provided, then no JSON-formatted access logging will be performed</LI>
 *   <LI>"--ldapDebugLogToStandardOut" -- Indicates that LDAP debug log
 *       information should be written to standard output.  This cannot be
 *       provided in conjunction with the "--ldapDebugLogFile" argument.  If
 *       neither argument is provided, then no debug logging will be
 *       performed.</LI>
 *   <LI>"-d {path}" or "--ldapDebugLogFile {path}" -- specifies the path to a
 *       file that should be used as a server LDAP debug log.  This cannot be
 *       provided in conjunction with the "--ldapDebugLogToStandardOut"
 *       argument.  If neither argument is provided, then no debug logging will
 *       be performed.</LI>
 *   <LI>"-s" or "--useDefaultSchema" -- Indicates that the server should use
 *       the default standard schema provided as part of the LDAP SDK.  If
 *       neither this argument nor the "--useSchemaFile" argument is provided,
 *       then the server will not enforce schema compliance.</LI>
 *   <LI>"-S {path}" or "--useSchemaFile {path}" -- specifies the path to a file
 *       or directory containing schema definitions to use for the server.  If
 *       neither this argument nor the "--useDefaultSchema" argument is
 *       provided, then the server will not enforce schema compliance.  If
 *       the specified path represents a file, then it must be an LDIF file
 *       containing a valid LDAP subschema subentry.  If the path is a
 *       directory, then its files will be processed in lexicographic order by
 *       name.</LI>
 *   <LI>"--doNotValidateSchemaDefinitions" -- indicates that the server should
 *       not perform any validation for the custom schema provided using the
 *       --useSchemaFile argument.  If this argument is not used and a custom
 *       schema is configured, then the server will validate that schema and
 *       report errors or warnings for any issues that it identifies with that
 *       schema.</LI>
 *   <LI>"--doNotGenerateOperationalAttributes" -- indicates that the server
 *       should not maintain any operational attributes (including entryDN,
 *       entryUUID, subschemaSubentry, creatorsName, createTimestamp,
 *       modifiersName, and modifyTimestamp) in entries.</LI>
 *   <LI>"-I {attr}" or "--equalityIndex {attr}" -- specifies that an equality
 *       index should be maintained for the specified attribute.  The equality
 *       index may be used to speed up certain kinds of searches, although it
 *       will cause the server to consume more memory.</LI>
 *   <LI>"-Z" or "--useSSL" -- indicates that the server should encrypt all
 *       communication using SSL.  If this is provided, then the
 *       "--keyStorePath" and "--keyStorePassword" arguments must also be
 *       provided, and the "--useStartTLS" argument must not be provided.</LI>
 *   <LI>"-q" or "--useStartTLS" -- indicates that the server should support the
 *       use of the StartTLS extended request.  If this is provided, then the
 *       "--keyStorePath" and "--keyStorePassword" arguments must also be
 *       provided, and the "--useSSL" argument must not be provided.</LI>
 *   <LI>"-K {path}" or "--keyStorePath {path}" -- specifies the path to the JKS
 *       key store file that should be used to obtain the server certificate to
 *       use for SSL communication.  If this argument is provided, then the
 *       "--keyStorePassword" argument must also be provided, along with exactly
 *       one of the "--useSSL" or "--useStartTLS" arguments.</LI>
 *   <LI>"-W {password}" or "--keyStorePassword {password}" -- specifies the
 *       password that should be used to access the contents of the SSL key
 *       store.  If this argument is provided, then the "--keyStorePath"
 *       argument must also be provided, along with exactly one of the
 *       "--useSSL" or "--useStartTLS" arguments.</LI>
 *   <LI>"--keyStoreType {type}" -- specifies the type of keystore represented
 *       by the file specified by the keystore path.  If this argument is
 *       provided, then the "--keyStorePath" argument must also be provided,
 *       along with exactly one of the "--useSSL" or "--useStartTLS" arguments.
 *       If this argument is not provided, then a default key store type of
 *       "JKS" will be assumed.</LI>
 *   <LI>"--generateSelfSignedCertificate" -- indicates that the server should
 *       generate a self-signed certificate to use for SSL or StartTLS
 *       communication.  If this argument is provided, then exactly one of the
 *       "--useSSL" or "--useStartTLS" arguments must also be specified.</LI>
 *   <LI>"-P {path}" or "--trustStorePath {path}" -- specifies the path to the
 *       JKS trust store file that should be used to determine whether to trust
 *       any SSL certificates that may be presented by the client.  If this
 *       argument is provided, then exactly one of the "--useSSL" or
 *       "--useStartTLS" arguments must also be provided.  If this argument is
 *       not provided but SSL or StartTLS is to be used, then all client
 *       certificates will be automatically trusted.</LI>
 *   <LI>"-T {password}" or "--trustStorePassword {password}" -- specifies the
 *       password that should be used to access the contents of the SSL trust
 *       store.  If this argument is provided, then the "--trustStorePath"
 *       argument must also be provided, along with exactly one of the
 *       "--useSSL" or "--useStartTLS" arguments.  If an SSL trust store path
 *       was provided without a trust store password, then the server will
 *       attempt to use the trust store without a password.</LI>
 *   <LI>"--trustStoreType {type}" -- specifies the type of trust store
 *       represented by the file specified by the trust store path.  If this
 *       argument is provided, then the "--trustStorePath" argument must also
 *       be provided, along with exactly one of the "--useSSL" or
 *       "--useStartTLS" arguments.  If this argument is not provided, then a
 *       default trust store type of "JKS" will be assumed.</LI>
 *   <LI>"--maxConcurrentConnections {num}" -- specifies the maximum number of
 *       concurrent connections that the server will allow.</LI>
 *   <LI>"--sizeLimit {num}" -- specifies the maximum number of entries that
 *       the server will return for a single search operation.</LI>
 *   <LI>"--passwordAttribute {attr}" -- specifies an attribute that will hold
 *       user passwords.</LI>
 *   <LI>"--defaultPasswordEncoding {scheme}" -- specifies the name of the
 *       default scheme that the server will use to encode clear-text
 *       passwords.  Allowed values include MD5, SMD5, SHA, SSHA, SHA256,
 *       SSHA256, SHA384, SSHA384, SHA512, SSHA512, CLEAR, BASE64, and HEX.</LI>
 *   <LI>"--allowedOperationType {type}" -- specifies a type of operation that
 *       the server will allow.  Allowed values include add, bind, compare,
