*FYI:*
I have used gschem for years and I encountered a bug that cost me an
embarrassing amount of time to resolve.
After a schematic editing session I closed the schematic. When I next tried
to reopen it, it failed to open with an error of "failed: Tried to attach a
non-text item as an attribute."

The error was hard to catch in the 27 part schematic. The problem is the
"2" in the last character of the last "T" line of the part. The "2" means
that the next "2" lines are text - except
that that is wrong. There is only one text line and gschem failed when it
encountered the "}".

It would certainly have been nice if gschem had displayed the offending
line, part or a useful error. Also what would have been nice, but is
absent, would be a --verbose option that printed
each part just before it was parsed.
