 Fortunately Spack handles this automatically upon install from a binary cache.
 But when you build binaries that are intended to be shared, there is one thing you have to keep in mind: Spack can relocate hard-coded paths in binaries *provided that the target prefix is shorter than the prefix used during the build*.
 
-The reason is that binaries typically embed these absolute paths in string tables, which is a list of null terminated strings, to which the program stores offsets.
+The reason is that binaries typically embed these absolute paths in string tables, which is a list of null-terminated strings, to which the program stores offsets.
 That means we can only modify strings in-place, and if the new path is longer than the old one, we would overwrite the next string in the table.
 
 To maximize the chances of successful relocation, you should build your binaries in a relatively long path.
