//hostname/dir1/dir2/dir3/file. (Windows does this too, with
QNX is one of those variants. On QNX4 with the FLEET distributed processing protocol,
// followed by a number refers to that node. So
//1/usr/pvcs on any node refers to the file
/usr/pvcs on node 1.

//aaaa/bbbb/cccc/nnnn - at where: aaaa = server name or IP address; bbbb = folder from the logical root of the domain aaaa (web servers can handle this dynamically); cccc = bbbb subfolder; nnnn = nth subfolder.
