[julia-users] REQUIRES and a specific branch?

[Seth]

I find myself frequently using features in other packages that haven't been 
tagged yet. Is there a way to specify in REQUIRES that, say, the master 
branch of the package should be used instead of the latest tagged version? 
This way others, including Travis and Coveralls, can get the correct 
functionality until the maintainers create a new tag for the required 
package.
