What governs the Package/Deploy/Quick Deploy Solution commands

I have inherited a Sharepoint 2007 web part project, with two branches in SVN.

When I load the trunk branch SLN into VS2008 and right click on the solution I see the following commands.

Build Solution
Rebuild Solution
Package Solution
Deploy Solution
Quick Deploy Solution >
Retract Solution
Clean Solution
... etc.

But when I view an old support branch, which is a few months old I only see the following:

Build Solution
Rebuild Solution
Clean Solution
... etc.

Where do th开发者_JS百科e Package/Deploy/Quick Deploy/Retract commands come from?

Ok, the answer to this is ridiculous. It turns out that if you use Solution Folders to tidy up your Sharepoint application, then VSeWSS loses the Package, Deploy, etc. commands.

Bad Microsoft! In your bed!
