URLs are used when they match the criteria given by the user.

If they put it on the command line explicitly, it gets used.  If it's 
an obvious distribution filename at the end of the URL, the version 
info is used to determine whether it's relevant.

Otherwise, it has to have a '#egg' tag to indicate what project and 
version the link is for...  and then it'll get used if it matches the 
version spec that's being searched for.

Usually, an SVN or other revision control link is going to have an 
'#egg=myproject-dev' tag, meaning "this is a URL for version 'dev' of 
'myproject'", so it'll only be downloaded if it's the only link, OR 
if the user explicitly requests a version matching 'dev', and there's 
nothing with a higher version to match.

The doc you want for that is this one, actually:
