function Invoke-PMInstall { <# .SYNOPSIS Installs a ProgramManager package. .DESCRIPTION Invokes an installation process on a ProgramManager.Package which has been earlier added to the database. .PARAMETER PackageName The name of the ProgramManager package to install. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .EXAMPLE PS C:\> Invoke-PMInstall -Name "notepad" This command will install the package named "notepad", executing any scriptblocks along with it. .EXAMPLE PS C:\> Get-PMPackage "notepad" | Invoke-PMInstall This command supports passing in a ProgramManager.Package object, by retrieving it using Get-PMPacakge for example.
