New deployment feature in MOSS 2007

I am into Moss 2007 developement team, Most of my team mates developed lot of stuff, but they do the deployment in old style like xcopy deployment. I have search lot of blogs and MSDN, finally i got it , how to deploy webparts,features , templates using new deployment feature (Solution deployment). I like to thank to Andrew cornelly,who showed some light , how to deploy a sharepoint solution using solution file.
Sharepoint webparts/Templates/Features can be deployed thru WSP File.This is nothing but a cab file.Generally cab file can be created using MAKECAB.EXE (You can download this microsoft site).This makecab.exe looks for DDF file(the file ends with .ddf) which is input for makecabe.exe produces a cab/.WSP file.
DDF file looks like below....

;*** SPSolutions.SharePoint.FIM MakeCab Directive
;
.OPTION Explicit ; Generate errors
;.Set CabinetNameTemplate=MyEventHandler.wsp
.Set DiskDirectoryTemplate=CDROM
.Set CompressionType=MSZIP
.Set UniqueFiles=Off
.Set Cabinet=On
.Set DiskDirectory1=Package
