Changes to snapshot directory

[Andrew Cagney]

I'm looking to change GDB's snapshots/ directory.  At present we've:

	ftp://sources.redhat/com/pub/gdb/snapshots/branch/
	ftp://sources.redhat/com/pub/gdb/snapshots/current/

where the first directory contains tarballs from the most recent branch, 
and the latter tarballs from the mainline.

The problem I see with this is that it is hard to track a snapshot 
series vis:

	gdb-6.2.50 -> gdb-6.2.90 -> gdb-6.3 -> gdb-6.3.1

you need to ``just know'' that half is found in current/ and half is 
found in branch/.

I can think of two alternatives:

- flatten things - snapshots/
- have separate release series directories -  6.2, 6.3, ...

I've a vague preference for the former,
thoughts?
