.ps1 Script for Packaging of SharePoint 2010 Application.

How to Deploy application on Client Machine using Power-cell Scripting ?

Steps : 

1) Take a backup of application from Site Settings ->Save Site as Template. Download .wsp at local machine.
2) Now put .wsp ,.ps1 and installer in same folder.

in installer.Bat file we have to write
============================================

cd /d %~dp0

%WINDIR%\System32\WindowsPowerShell\v1.0\powershell.exe -file .\Install.ps1 %1 %2 %3 %4 "%~dp0

pause

============================================
3) Now here is .ps1 script for application.
 ( We can direct run the .Ps1 by right click on .Ps1 ->Run with PowerCell )
