Provide version to virtual package.

[Robert David <robert.david.public@gmail.com>]

Hi, I need to pack evolution and evolution-data-server with some extras 
patched. But didnt find a way how to do that best to be user friendly.

The best for me is renaming the package evolution -> evolution-xyz and all the 
included libs etc (I need to keep it consistent so I will rename all the 
included packages). I use "Replaces:" "Provides:" "Conflicts:" but as I read 
virtual package doesnt recognize version, so it leads to dependency conflicts 
with some other packages using evolutin/libs. Is there a way to define virtual 
package version? I mean some packager way, not that anyone who want to install 
this package would need to install that in a different way than normal.

Another way is to name that evolution_2.24.2-0xyz1.deb but then if I make an 
repo then there will be no easy way how to install or link that or isnt? I 
though about things like creating metapackage evolution-xyz that installs 
those packages, but I havent found a neat guide for making metapackage like 
this.

Thanks,
Robert David.
