An "alg" is simply a file (file.alg) that the benchmarking code runs.
You run it something like this:
ant run-task -Dtask.alg=/path/to/file.alg -Dtask.mem=1024M
For docs... there's the package.html in contrib/benchmark. LIA 2
(only via MEAP right now) also covers benchmark's alg syntax in an
appendix.
But you are close... oh, it actually looks like the output file (work/
enwiki.txt) could not be written. Does that directory (../work)
exist? (I think build.xml should have created it).

The xml file temp/enwiki-20070527-pages-articles.xml was downloaded
by "ant
get-enwiki expand-enwiki". The docs.file in extractWikipedia.alg and
wikipedia.alg points to it. The error message is regarding
work/enwiki.txt.
Is there a how to on this stuff? What is an alg?

You should download Wikipedia's XML file manually yourself,
uncompress it,
and then edit docs.file in that alg to point to it.
