I followed the wiki tutorial "Build nutch 0.9 with eclipse" and it worked
out great.

But I still haven't figured out what to do to build jar files of my own and
have "bin/nutch" use them. Anyone cares to explain?

My eclipse experience is only limited to "export" to a jar file. But
"bin/nutch" script uses tons of jar files! And I only made one single change
in SegmentReader, what do I do update only this thing?

Thanks in adv,
