  Yup, ArcInfo AML. I threw it together and posted it to the mapserver
list last February because I wanted to give something to the list before I
asked my newbie questions. I'm still asking the questions...

Anyway, take a look at my code at:

It translates the coverages into shapefiles, and makes a mapfile and
template html files which match the mapserver demo (minus the inset map).
It's not particularly forgiving, but then it doesn't do much damage.

It would probably take some changing for dealing with A/I libraries--I
don't have much experience with them.
