Describes the notation used for Windows PowerShell syntax in Help.

	The Get-Help cmdlet displays the parameter usage for a cmdlet. The Get-Help 
	cmdlet uses the following special symbols:

		Angle brackets (<>) indicate placeholder text. 
		Brackets ([]) indicate optional items. 
		Braces ({}) indicate a choice among values.

	Some cmdlets have more than one set of parameters. Distinct parameter sets 
	can share some parameters. The Get-Help cmdlet displays all the parameter 
	sets for a cmdlet.

	You can find additional information about a parameter in the parameter 
	description and in the parameter attribute table. To view complete 
	information about a parameter, use the Full or Parameter parameters of 

	Windows PowerShell cmdlet Help, Help topics, and other documentation use 
	the following notation for cmdlets in syntax descriptions. 

		<cmdlet name> -<Required Parameter name> <Required parameter Value>
					 [-<Optional Parameter name> <Optional Parameter Value>] 
					 [-<Optional Switch Parameter>] 
					 [-<Optional Parameter Name>] <Required parameter Value> 

	The following is the syntax for the New-Alias cmdlet.

		New-Alias [-Force] [-PassThru] [-Scope <string>] 
			[-Option {None | ReadOnly | Constant | Private | AllScope}] 
			[-Description <string>] [-Name] <string> [-Value] <string> 
			[-confirm] [-whatif] [<CommonParameters>]

	The syntax is capitalized for readability, but Windows Powershell is 

	Parameters appear in order. The order of parameters is significant only 
	when the parameter names are optional. If you do not specify parameter 
	names when you use a cmdlet, Windows PowerShell assigns values to 
	parameters by position and by type. 

	Parameter names are preceded by a hyphen (-). Switch parameters appear 
	without a value type. Other parameters appear with the Microsoft .NET 
	Framework type of the argument required or with an enumeration of 
	possible values. For more information about .NET Framework types, 

	Angle brackets (<>) indicate placeholder text. This text can describe the 
	type of an item (such as a string or a Process object). It can also be a 
	placeholder for one or more common parameters.

	Brackets ([]) indicate optional items. A parameter can be optional, or 
	the name of a required parameter can be optional. Switch parameters are 
	always optional. 

	Braces ({}) appear around the values of an enumeration. In the example of 
	the New-Alias cmdlet, the Option parameter can have any of the listed 

  Optional Items
	Brackets ([]) surround optional items. For example, in the New-Alias 
	cmdlet syntax description, the Scope parameter is optional. This is 
	indicated in the syntax by the brackets around the parameter name 
	and type:

		[-Scope <string>]

	Both the following examples are correct uses of the New-Alias cmdlet:

		New-Alias -Name utd -Value Update-TypeData
		New-Alias -Name utd -Value Update-TypeData -Scope global

	A parameter name can be optional even if the value for that parameter is 
	required. This is indicated in the syntax by the brackets around the 
	parameter name but not the parameter type, as in this example from the 
	New-Alias cmdlet:

		[-Name] <string> [-Value] <string>

	The following  commands correctly use the New-Alias cmdlet. The commands 
	produce the same result:

		New-Alias -Name utd -Value Update-TypeData
		New-Alias -Name utd Update-TypeData
		New-Alias utd -Value Update-TypeData
		New-Alias utd Update-TypeData

	If the parameter name is not included in the statement as typed, Windows 
	PowerShell tries to use the position of the arguments to assign the 
	values to parameters.

	The following example is not complete:

		New-Alias utd

	This cmdlet requires values for both the Name and Value parameters.

	In syntax examples, brackets are also used in naming and casting to 
	.NET Framework types. In this context, brackets do not indicate an 
	element is optional.

  Array Arguments 
	Brackets are also used in syntax descriptions to represent an array. 
	The following example shows the syntax for the Restart-Service cmdlet:

		Restart-Service [-Name] <string[]> [-Include <string[]>] 
			[-Exclude <string[]>] [-Force] [-PassThru] [-Confirm] [-WhatIf] 

	The Name parameter requires an argument. Specifically, it requires the 
	name of the service to be restarted. It can take a comma-separated list 
	of services, as in the following example:

		Restart-Service RasAuto, RasMan, RemoteAccess
