SHORT DESCRIPTION
    PackageManagement is an aggregator for software package managers.
    

LONG DESCRIPTION
    PackageManagement functionality was introduced in Windows PowerShell 5.0.

    PackageManagement is a unified interface for software package management systems; you
    can run PackageManagement cmdlets to perform software discovery, installation, and
    inventory (SDII) tasks. Regardless of the underlying installation technology,
    you can run the common cmdlets in the PackageManagement module to search for,
    install, or uninstall packages; add, remove, and query package repositories; and
    run queries on a computer to determine which software packages are installed.

    PackageManagement supports a flexible plug-in model that enables support for other 
    software package management systems.
 
    The PackageManagement module is included with Windows PowerShell 5.0 and later releases
    of Windows PowerShell, and works on three levels of package management
    structure:  package providers, package sources, and the packages themselves.

  PackageManagement Package Provider Bootstrapping and Dynamic Cmdlet Parameters

    By default, PackageManagement ships with a core bootstrap provider. You can install
    additional package providers as you need them by bootstrapping the providers;
    that is, responding to a prompt to install the provider automatically, from a
    web service. You can specify a package provider with any PackageManagement cmdlet;
    if the specified provider is not available, PackageManagement prompts you to bootstrap
    --or automatically install--the provider. In the following examples, if the
    Chocolatey provider is not already installed, PackageManagement bootstrapping installs
    the provider. 

        Find-Package –Provider Chocolatey <PackageName>

    If the Chocolatey provider is not already installed, when you run the
    preceding command, you are prompted to install it.

        Install-Package <Chocolatey package Name> -ForceBootstrap

    If the Chocolatey provider is not already installed, when you run the
    preceding command, the provider is installed; but because the ForceBootstrap
    parameter has been added to the command, you are not prompted to install it;
    both the provider and the package are installed automatically.

    When you try to install a package, if you do not already have the supporting
    provider installed, and you do not add the ForceBootstrap parameter to your
    command, PackageManagement prompts you to install the provider.
    
    Specifying a package provider in your PackageManagement command can make
    dynamic parameters available that are specific to that package provider. 
    When you run Get-Help for a specific PackageManagement cmdlet, a list of
    parameter sets are returned, grouping dynamic parameters for available
    package providers in separate parameter sets.
