Should be easy enough to do this without any cd-ing anywhere:
tar xzf ${WORK_DIR}/reuters21578.tar.gz -C ${WORK_DIR}/reuters-sgm
I'll patch it.

Great Sean, thanks.
This script also does rm -rf ${WORK_DIR} when it's done and I don't think it
should. It is helpful to leave the work directories around so that you don't
have to re-download the reuters tarfile and re-vectorize it should you want to
run lda after trying kmeans. It's also helpful also to leave these files around
for those curious to inspect the output files.
This behavior wasn't introduced in the patch, but I just noticed it while
testing.

> The examples in examples/bin create subdirectories (either work or
> mahout-work) in that directory and write to those subdirectories. This works
> fine if the current user has write access to examples/bin, but if not (such
> as in the case of the package generated by Bigtop, in which the files are
> installed to /usr/lib/mahout and owned by root), the examples can't run. This
> is causing BIGTOP-96, but needs to be fixed in Mahout. The patch I'm
> attaching changes all the references to work, examples/bin/work, and
> mahout-work to instead use /tmp/mahout-work-${USER}, which will be writeable.
