"By way of a test I took two similar clauses and saved
them to separate text files. I then used OpenOffice’s compare
function to show the changes. This was the output...
"Despite there being some commonality between the two clauses -
eg "may invoice" are the second and third words of both clauses,
OpenOffice simply marked the whole thing as a change. The clauses
are each less than 60 words - a markup should not be difficult. The
output is unhelpful and this sort of output from compare is not
unusual for OpenOffice."
