Package: barcode
Version: 0.98-1
Followup-For: Bug #320908
I worked a bit at this and figured out what it was. The codabar support dose
not include the T, N, *, and E characters. The patch adds these characters.
Also, the old behavior was to assume that the barcode begins with A and ends
with B. Most examples I've seen online seem to imply that T should be the
default end, so the patch changes the default ending from B to T.
