Request for review: GNU barcode

[Andreas Thienemann <andreas bawue net>]

hello all,

I need a bit of review on a gnu barcode, packaged as a rpm.

%description
The package is meant to solve most needs in barcode creation with a
conventional printer. It can create printouts for the conventional
product tagging standards: UPC-A, UPC-E, EAN-13, EAN-8, ISBN, as well
as a few other formats. Ouput is generated as either Postscript or
Encapsulated Postscript.

SPEC: http://home.bawue.de/~ixs/barcode/barcode.spec
SRPM: http://home.bawue.de/~ixs/barcode/barcode-0.98-1.src.rpm

I need a bit of advice on the -devel package.
barcode installs a .h and a .a file. Would it be sensible to package them 
into a -devel package or is it simply not worth it and they should be put 
into the main package?
Personally, I prefer the -devel package, but for two files it might simply 
be overkill.
Opinions?

thx,
 andreas
