+.SYNOPSIS
+	This script performs the installation or uninstallation of an application(s).
+	# LICENSE #
+	PowerShell App Deployment Toolkit - Provides a set of functions to perform common application deployment tasks on Windows. 
+	Copyright (C) 2017 - Sean Lillis, Dan Cunningham, Muhammad Mashwani, Aman Motazedian.

This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

+.DESCRIPTION
+	The script is provided as a template to perform an install or uninstall of an application(s).
+	The script either performs an "Install" deployment type or an "Uninstall" deployment type.
+	The install deployment type is broken down into 3 main sections/phases: Pre-Install, Install, and Post-Install.
+	The script dot-sources the AppDeployToolkitMain.ps1 script which contains the logic and functions required to install or uninstall an application.
+.PARAMETER DeploymentType
+	The type of deployment to perform. Default is: Install.
+.PARAMETER DeployMode
+	Specifies whether the installation should be run in Interactive, Silent, or NonInteractive mode. Default is: Interactive. Options: Interactive = Shows dialogs, Silent = No dialogs, NonInteractive = Very silent, i.e. no blocking apps. NonInteractive mode is automatically set if it is detected that the process is not user interactive.
+.PARAMETER AllowRebootPassThru
+	Allows the 3010 return code (requires restart) to be passed back to the parent process (e.g. SCCM) if detected from an installation. If 3010 is passed back to SCCM, a reboot prompt will be triggered.
+.PARAMETER TerminalServerMode
+	Changes to "user install mode" and back to "user execute mode" for installing/uninstalling applications for Remote Destkop Session Hosts/Citrix servers.
+.PARAMETER DisableLogging
+	Disables logging to file for the script. Default is: $false.
+.EXAMPLE
+    powershell.exe -Command "& { & '.\Deploy-Application.ps1' -DeployMode 'Silent'; Exit $LastExitCode }"
+.EXAMPLE
+    powershell.exe -Command "& { & '.\Deploy-Application.ps1' -AllowRebootPassThru; Exit $LastExitCode }"
+.EXAMPLE
+    powershell.exe -Command "& { & '.\Deploy-Application.ps1' -DeploymentType 'Uninstall'; Exit $LastExitCode }"
+.EXAMPLE
+    Deploy-Application.exe -DeploymentType "Install" -DeployMode "Silent"
+.NOTES
+	Toolkit Exit Code Ranges:
+	60000 - 68999: Reserved for built-in exit codes in Deploy-Application.ps1, Deploy-Application.exe, and AppDeployToolkitMain.ps1
+	69000 - 69999: Recommended for user customized exit codes in Deploy-Application.ps1
+	70000 - 79999: Recommended for user customized exit codes in AppDeployToolkitExtensions.ps1
