Use older VS Extensions with VS-2013

Question

How does Visual Studio identifies, a particular VS Extension should be installed for which version.

I am trying to use an older extension with VS-2013 at my own risk. As .VSIX internally is just a zip file I should be able to tweak version info in definition file.

Any pointers in this direction please.

All supported VS versions are listed in the .vsixmanifest file inside the "zip" file. There are v1 (VS 2010+) and v2 (VS 2012+) slightly different schemes of this file. In v2 look for "Version Range" and in v1 look for "SupportedProducts".
