Version information inside the driver's jar file

Hi,

if the driver's jar file has been renamed, the only way to find out the driver's version is to actually make a
connectionusing that driver.  

I would like to suggest to add an entry to the manifest file that shows the driver's version so that it is easier to
findthat out (e.g. when a .jar file gets bundled within an application) 

Something like:

Implementation-Title: PostgreSQL JDBC4 Driver
Implementation-URL: http://jdbc.postgresql.org
Implementation-Version: 8.4-701

What do you think of that?

Regards
Thomas
