Modifying SPThemes.xml Programmatically to deploy new Themes MOSS 2007 (WSS 3.0)

One of my colleague was looking for modifying the SPThemes.xmlfile programmatically instead of editing it manually on each and every server. So that the deployment of new themes could be very easy thru the Solution Deployment/Packaging way. All we need is a Feature Receiver for that. In case if you have not already seen the VSEwss 1.3 here check it out, there is a ready made codebehind available that be reused to deploy your custom Themes in sharepoint 2007 (wss 3.0) using the feature / Solution deployment packaging approach. Following is the source code from the Feature receiver from the VSeWSS project (https://www.microsoft.com/downloads/details.aspx?FamilyID=0A87658F-20B8-4DCC-AD7A-09AD22641F3A&displaylang=en)

NOTE: These 10 Theme Features are FARM LEVEL Features and you can find these Features in the Central Admin box under the Operation tab under Farm level Features:
