/**
* The Debug class contains several useful debugging class (static)
* methods. It cannot be instantiated.
* Some methods give useful information, such as amount of memory used,
* enabling instruction tracing, displaying object hierarchy, and dumping
* the contents of a raw byte buffer.
*
*
* Another type of debug supports two kinds of methods; those that inform
* whether a debug option is set or not; and those that output the specified
* string to the debugOut stream when the associated debug value
* is set.
*
* The Debug class checks in the object returned by System.getProperties
* for the name ldap.debug which has the following valid values:
*
* VMtraceInstructions - Enables instruction trace
* VMtraceMethodCalls - Enables method call trace
* trace - Displays a string if the named property is set
* dumpBuffer - Displays raw buffer dumps
* dumpObject - Displays information about an object.
* The following property values can limit the information displayed. If
* dumpObject is selected, all those listed below are also selected
* dumpObjectHierarchy - Displays object hierarchy
* dumpObjectConstructors - Displays object constructors
* dumpObjectFields - Displays object fields
* dumpObjectMethods - Displays object methods
*
*
* If multiple values are desired, they are separated by semicolon's, i.e.
*
* java -Dldap.debug=serverprogress;echodebug TServer -tree junk
*
* The values are case insensitive. Invalid values are ignored.
*
* The ldap_debug variable allows debug code to be excluded
* from a compile by codeing something like the following:
*
* if( Debug.LDAP_DEBUG) trace(trace.referrals, "Entering referral code");
*
