Updating Module Details in web config

Hi,

Right now we are updating below module details i.e public key token,version in the site web.config file manually after building the solution.

<add name="ModuleName" type="aa.bb.cc.Modules.LoginRedirectModule,aa.bb.cc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=0b4d73b6b74931f5" /> 

But we want to automate this i.e after deploying the wsp,the above details should be available in site web config under module section.

Please let me know how this can be achived,we are using visual studio 2012

Regards,

Sudheer
