IWizard: copy temporary file to the project folder

Hello,

From my wizard, I want to copy a file from the temporary folder generated by the vstemplate to the project folder. As far as I know, the template generate the project depending on include directive: but what if I want to add an hidden file in my project folder ?

The file is in my zipped template, but is not copied if I don't use Include directive in csproj. So, is there a way to copy a file from the temporary generated template folder to the project folder ?

I need it to be done BEFORE the project includes directives are processed.

Thanks in advance for your help.
