075/**
076 * This class provides a tool that can be used to perform repeated modifications
077 * in an LDAP directory server using multiple threads.  It can help provide an
078 * estimate of the modify performance that a directory server is able to
079 * achieve.  The target entry DN may be a value pattern as described in the
080 * {@link ValuePattern} class.  This makes it possible to modify a range of
081 * entries rather than repeatedly updating the same entry.
082 * <BR><BR>
083 * Some of the APIs demonstrated by this example include:
084 * <UL>
085 *   <LI>Argument Parsing (from the {@code com.unboundid.util.args}
086 *       package)</LI>
087 *   <LI>LDAP Command-Line Tool (from the {@code com.unboundid.util}
088 *       package)</LI>
089 *   <LI>LDAP Communication (from the {@code com.unboundid.ldap.sdk}
090 *       package)</LI>
091 *   <LI>Value Patterns (from the {@code com.unboundid.util} package)</LI>
092 * </UL>
093 * <BR><BR>
094 * All of the necessary information is provided using command line arguments.
095 * Supported arguments include those allowed by the {@link LDAPCommandLineTool}
096 * class, as well as the following additional arguments:
097 * <UL>
098 *   <LI>"-b {entryDN}" or "--targetDN {baseDN}" -- specifies the DN of the
099 *       entry to be modified.  This must be provided.  It may be a simple DN,
100 *       or it may be a value pattern to express a range of entry DNs.</LI>
101 *   <LI>"-A {name}" or "--attribute {name}" -- specifies the name of the
102 *       attribute to modify.  Multiple attributes may be modified by providing
103 *       multiple instances of this argument.  At least one attribute must be
104 *       provided.</LI>
105 *   <LI>"-l {num}" or "--valueLength {num}" -- specifies the length in bytes to
106 *       use for the values of the target attributes.  If this is not provided,
107 *       then a default length of 10 bytes will be used.</LI>
108 *   <LI>"-C {chars}" or "--characterSet {chars}" -- specifies the set of
109 *       characters that will be used to generate the values to use for the
110 *       target attributes.  It should only include ASCII characters.  Values
111 *       will be generated from randomly-selected characters from this set.  If
112 *       this is not provided, then a default set of lowercase alphabetic
113 *       characters will be used.</LI>
114 *   <LI>"-t {num}" or "--numThreads {num}" -- specifies the number of
115 *       concurrent threads to use when performing the modifications.  If this
116 *       is not provided, then a default of one thread will be used.</LI>
117 *   <LI>"-i {sec}" or "--intervalDuration {sec}" -- specifies the length of
118 *       time in seconds between lines out output.  If this is not provided,
119 *       then a default interval duration of five seconds will be used.</LI>
120 *   <LI>"-I {num}" or "--numIntervals {num}" -- specifies the maximum number of
121 *       intervals for which to run.  If this is not provided, then it will
122 *       run forever.</LI>
123 *   <LI>"--iterationsBeforeReconnect {num}" -- specifies the number of modify
124 *       iterations that should be performed on a connection before that
125 *       connection is closed and replaced with a newly-established (and
126 *       authenticated, if appropriate) connection.</LI>
127 *   <LI>"-r {modifies-per-second}" or "--ratePerSecond {modifies-per-second}"
128 *       -- specifies the target number of modifies to perform per second.  It
129 *       is still necessary to specify a sufficient number of threads for
130 *       achieving this rate.  If this option is not provided, then the tool
131 *       will run at the maximum rate for the specified number of threads.</LI>
132 *   <LI>"--variableRateData {path}" -- specifies the path to a file containing
133 *       information needed to allow the tool to vary the target rate over time.
134 *       If this option is not provided, then the tool will either use a fixed
135 *       target rate as specified by the "--ratePerSecond" argument, or it will
136 *       run at the maximum rate.</LI>
137 *   <LI>"--generateSampleRateFile {path}" -- specifies the path to a file to
138 *       which sample data will be written illustrating and describing the
139 *       format of the file expected to be used in conjunction with the
140 *       "--variableRateData" argument.</LI>
141 *   <LI>"--warmUpIntervals {num}" -- specifies the number of intervals to
142 *       complete before beginning overall statistics collection.</LI>
143 *   <LI>"--timestampFormat {format}" -- specifies the format to use for
144 *       timestamps included before each output line.  The format may be one of
145 *       "none" (for no timestamps), "with-date" (to include both the date and
146 *       the time), or "without-date" (to include only time time).</LI>
147 *   <LI>"-Y {authzID}" or "--proxyAs {authzID}" -- Use the proxied
148 *       authorization v2 control to request that the operation be processed
149 *       using an alternate authorization identity.  In this case, the bind DN
150 *       should be that of a user that has permission to use this control.  The
151 *       authorization identity may be a value pattern.</LI>
152 *   <LI>"--suppressErrorResultCodes" -- Indicates that information about the
153 *       result codes for failed operations should not be displayed.</LI>
154 *   <LI>"-c" or "--csv" -- Generate output in CSV format rather than a
155 *       display-friendly format.</LI>
156 * </UL>
