@scortier We also need to encapsulate storing of the current version, build, etc. in this package only. So the version package should also be able to return current version.

@ravisuhag Do we need to ask user for their current binary version or should the package itself need to find it ?

These vars can be at this package level only but we can expose a function for users to set them up. Package users can then maybe decide if they want to use go build flags to directly set up build and version or use the function to assign them.
Another way could be the version package expect users to send this explicitly.
WDYT?

Currently , moving forward with the approach of user providing the current version.
