[boost] library usage statistics

Looking at the discussion regarding multi-array, I'm thinking I'd like to know how many people/projects are using the current version. It's been there for ever and hardly ever gets an update. This indicates to me that the current usage is very small - or that the library is currently close to perfect! I don't have a specific need for this, but I find myself wanting this information all the time and I don't see a way to get it. If anyone has any ideas about how to do this, I'd be curious to hear them. Robert Ramey
