Convert .rules file to Visual Studio 2010 .targets file

I'm trying to se flex and bison in Visual Studio 2010开发者_StackOverflow中文版. I found a .rules file on the web, but it is only useable in vs2k5/2k8. How do I convert it to the newer, '.targets' format?

Here's the file:

Are there any tools for this?

Thank you!

I used the TinyMath project available in the below link to test that.
http://msdn.microsoft.com/en-us/library/aa730877%28vs.80%29.aspx VS2010 automatically converts that to the .targets format.

Visual studio 2010 does this automatically when you migrate the project.
