Real world example: 28 instances of the same symbol, with the same =
source attribute, spread across 6 schematics. All of the 6 are sources =
in other symbols, some of which have multiple instances themselves. =
source=3D tells you how to go down in the hierarchy, but from a =
particular schematic there are many paths up. Gschem/lepton-schematic =
remembers the =E2=80=9CHd=E2=80=9D path you used to get to where you =
are, so =E2=80=9CHu=E2=80=9D from any particular view is well defined.
