[GenABEL-dev] Adding 'tags' directories to the SVN repo

[Yurii Aulchenko]

Having tags is a good idea indeed.

Something to keep in mind: RForge is doing nightly builds under
different platforms, assuming that any directory under 'pkg' is a
regular package source. This is a tool of potentially great value.
Maybe RForge docs and consulting RForge team on how to best arrange
tags is a good idea.

Bw,
Yurii
