How to include external files in multi-project .vstemplate?

Question

Hello,

I'm creating a VS2010 multi project template and I'm trying to make add a file (.hgignore) to the solution (not into a project) from the vstemplate.

I tried this but it doesn't work :

< VSTemplate Version="3.0.0" xmlns="http://schemas.microsoft.com/developer/vstemplate/2005" Type="ProjectGroup">

< TemplateData>...< /TemplateData>

< TemplateContent >

< ProjectItem> .hgignore < /ProjectItem >

< ProjectCollection >

< ProjectTemplateLink ProjectName="$safeprojectname$.xxx">....< /ProjectTemplateLink> < ProjectTemplateLink ProjectName="$safeprojectname$.xxx">....< /ProjectTemplateLink>

< /ProjectCollection>

< /TemplateContent>

< /VSTemplate>

Thank you very much

PS : I can't manage to make correct XML tag in the editor so I had to add white space...
