/**
* This class provides a simple tool that can be used to perform add, delete,
* modify, and modify DN operations against an LDAP directory server. The
* changes to apply can be read either from standard input or from an LDIF file.
*
* Some of the APIs demonstrated by this example include:
*
*
Argument Parsing (from the {@code com.unboundid.util.args}
* package)
*
LDAP Command-Line Tool (from the {@code com.unboundid.util}
* package)
*
LDIF Processing (from the {@code com.unboundid.ldif} package)
*
*
* The behavior of this utility is controlled by command line arguments.
* Supported arguments include those allowed by the {@link LDAPCommandLineTool}
* class, as well as the following additional arguments:
*
*
"-f {path}" or "--ldifFile {path}" -- specifies the path to the LDIF
* file containing the changes to apply. If this is not provided, then
* changes will be read from standard input.
*
"-a" or "--defaultAdd" -- indicates that any LDIF records encountered
* that do not include a changetype should be treated as add change
* records. If this is not provided, then such records will be
* rejected.
*
"-c" or "--continueOnError" -- indicates that processing should
* continue if an error occurs while processing an earlier change. If
* this is not provided, then the command will exit on the first error
* that occurs.
*
"--bindControl {control}" -- specifies a control that should be
* included in the bind request sent by this tool before performing any
* update operations.
*
