That seems just the kind of thing that could be co-opted to my
purposes, but as you say the cabal file format doesn't seem to mention
how I'd go about setting my tag field. Trying "Tag: dougal1" didn't
work, as I suspected ;-)

In the mean time I will try Stephen Tetley's approach of renaming the
package instead of the version.
