Message:

Firefox-58.0 and rustc-1.22.1. Firefox now sometimes needs libnotify to report success during the install (I managed some installs without that being present, others barfed at the end). This version of firefox has felt like 'In the beginning was the plan, ... and the darkness was upon the face of the workers ...' I hope it will be less painful for anybody using it.

+        Repeated builds of this package on the same machine show a wide range
+        of build times. Some of this might be due to variations in downloading
+        the required cargo files if they are not already present, but this does
+        not seem to adequately explain the variations. Also, both the builder
+        and the user running the install will need to download the cargo crates

+        If you use a DESTDIR method to install, you will only need to download

+        install time (but using extra space for the install). Similarly if you

+        ./x.py install</command> - but those methods are dangerous.
