Are there any easy-to-use #JBIG2 tools for #Linux?

#GIMP doesn't seem to support it (yet?), and I just can't wrap my head around how to use jbig2enc -- it spits out some data to STDOUT that 'file' can't identify.
I just find the concept of lossy bilevel images compression fascinating, and I'd love to play with it to see how badly it would butcher something like a Floyd-Steinberg dithered image (and how much compression it'd actually accomplish)

Addendum: It may be that I'm using jbig2enc just fine, but that neither file, nor GIMP, nor nsxiv, nor ImageMagick know how to work with the file?!? Or just that it's not encoded in a way that any program I currently know of can read it?!?

Hola [email protected],
Do you know of any good programs to view JBIG2 files in Linux?
Also, is there any way to set the compression factor in jbig2enc's jbig2 executable?
Thanks! :D

Addendum2:
Imagemagick is supposed to support JBIG2, but when I ask it to convert a file to JBIG2, it just gives me a JPEG or PDF (whatever the source image was) :/

Addendum 3: I was able to get jbigkit to work, which is JBIG1-only (and by consequence, lossless-only).
It was still pretty cool, and compressed bi-level images better than PNG, GIF, or any TIFF mode GIMP has access to. :D
