Thanks for clarifying these terms!  I know this may seem obvious, but as 
the fact that even Vladimir and DJ seem to have subtly different notions 
of a "component" shows, this can be tricky to get right.

So, if I understand this correctly,

* both libgeda's "complex" and gnetlist's "netlist" should actually be 
called a "component"

* the component library should actually be called symbol library

* a "package", an "element", and a "part" are the same thing, just from 
the gnetlist, PCB, and BOM point of view, respectively

* "component" relates to "symbol" as "package" or "element" relate to 
"footprint"

* a package comprises exactly those components which share a common refdes

* components sharing the same refdes can't have different device= 
attributes

Do you agree with these corollaries?  If you think any of these isn't 
correct, please let me know.
