Patch for being able to call gprinstall

[Manuel Gómez]

I don't know if there is a better way to send a patch to the project, 
but I haven't seen any feature similar to a pull request in Savannah, so 
I send here my patch.

This is for being able to call gprinstall with the project file or `alr 
install` on the crate.
