Ahhh....

Just barely, and just recently.  And not for much total time yet.

Well, diptrace must have the same problem.  You either need to map from one library to the other, or export enough of the library that you can import into the new library the required symbols.

Ahhhh^2....

That makes a lot of sense, even when the file format *is* well documented.  The question is then, how much munging does it take to transmute diptrace ascii exchange format into gEDA stuff.

Now, why someone would do open source hardware with closed source tools is a mystery to me... but anyway.... so far in a total of 30 minutes of Eagle usage I've discovered: 1) the crippleware version only allows a single schematic sheet, leading people to create unreadable glop, and 2) printing is truly bizarre.  I can't imagine someone going from gEDA to the free/crippled version of Eagle.  And as to going to the commercial version, OK I can see some customer requiring that, but isn't that Eagle's problem?  After all, nobody is hiding gEDA's file formats.
