============================================================================
Usage: $self -n buildnum [-s SourceTree] [-t TargetTree] [-f SnapList]  
                  [-y BuildBranch] [-B bldinfo] [-L] [-i] [-d]
	-n Build Number : The Build Number you snapshot
	-s Source Tree : Source Tree
	-t Target Tree : Target Tree
	-f SnapList : A snaplist file contain which files or dirs excluded
	-y BuildBrahcn : Branch to snap the build from. Default %_BuildBranch% 
	-B bldinfo : A bldinfo file should be create after snapshot
	-L : Include robocopy log into logfile
	-i : Incremental 
        -d : Debug. Display the robocopy command without running it. Useful
             when you  encountered the error and willing debug it.   
        -N : use NET access to release server(s) to determine the snap location.
             Default behavior is rely on DFS. 
        -B : specify the release server to form the snap location. Only used when -N
             flag set 


	-? Displays usage

Example:
1. Snapshot US 2121
$0 -n 2121
2. Snapshot US 2222 with userlst.txt incrementally
$0 -n 2222 -f userlst.txt -i
3. Snapshot US 2233 from d:\\nt8.binaries.x86fre to f:\\nt9.binaries.x86fre 
   with userlst.txt and store buildnumber and time stamp to mynote.txt.
$0 -n 2233 -s d:\\nt8.binaries.x86fre -t f:\\nt9.binaries.x86fre -f userlst.txt -B mynote.txt
4. Dummy snap the idx02 build in the Razzle enlisted in main branch.
$0 -n 3505 -b idx02 -d

=head1 NAME
B<SnapBin> - Snapshot US Binaries tree to INTL

=head1 SYNOPSIS

	&SnapBin::PrepareRoboCopyCmd;
	&SnapBin::ExecuteRoboCopy;
	&SnapBin::ParseLogFile;
	&SnapBin::CreateBldInfo;

=head1 DESCRIPTION

	According SnapList,
	PrepareRoboCopyCmd will prepare the command, such as:
		Robocopy /MIR /S /E $SourceTree $TargetTree /XD xxxx /XF xxxx /LOG+:$ENV{logfile}.temp
	ExecuteRoboCopy execute the command and verify its log.
	And, ParseLogFile will append temp logfile to $ENV{logfile} and generate a separate list into log.
	Final, create BldInfo file in nt root.

=head1 INSTANCES

=head2 $SourceTree
	US Tree, default is \\\\ntdev\\release\\<_BuildBranch>\\usa\\<BuildNum>\\<_BuildArch><_BuildType>\\bin
=head2 $TargetTree
	INTL Tree, default is _NTTREE
=head2 $SnapList
	Snap List FileName, default is SnapList.txt
=head2 $BuildNum
	Build Number, necessary defined.  No default value
=head2 %SnapList
	The hash stored by HashText::Read_Text_Hash from file $SnapList.
=head2 $RoboCopyCmd
	The command for ExecuteRoboCopy execute
=head1 METHODS

=head2 PrepareRoboCopyCmd
	$SnapBin::SourceTree = "f:\\foo";
	$SnapBin::TargetTree = "f:\\bar";
	$SnapBin::SnapList = "mylist.txt"; # equal to '-' if no exclude list file
	&SnapBin::PrepareRoboCopyCmd;
	system("$SnapBin::RoboCopyCmd");

=head2 ExecuteRoboCopy
	$SnapBin::SourceTree = "f:\\foo";
	$SnapBin::TargetTree = "f:\\bar";
	$SnapBin::RoboCopyCmd = "Robocopy /S $SnapBin::SourceTree $SnapBin::TargetTree";
	&SnapBin::ExecuteRoboCopy;

=head2 ParseLogFile
	system("robocopy f:\\temp F:\\tempbak /LOG:abc.log");
	&SnapBin::ParseLogFile("abc.log");
