<br><font size=2 face="Courier New">The legal language for the AMPL-Solver
Library only appears, as far as I'm aware, in the source and header files
themselves. As an example, the notice at the beginning of asl.h is
copied below. Perhaps this doesn't qualify as release under a certified
open-source license, but it seems to be sufficient to enable people to
build and distribute AMPL-solver drivers. At least, I am pretty sure
that every connection from AMPL to one of the solvers listed at </font><a href=http://www.ampl.com/solvers.html><font size=2 color=blue face="Courier New"><u>www.ampl.com/solvers.html</u></font></a><font size=2 face="Courier New">

I would add that the entire AMPL-solver library is open-source, available
at<br>
http://www.netlib.org/ampl/solvers/. Instructions for using the library
to<br>
write an AMPL-solver "driver" are at http://www.ampl.com/hooking.html.
Source<br>
for many previously written drivers is also available, in the same location
as<br>
the library source, so it's often possible to modify an existing driver
rather<br>
than start from scratch.<br>
<br>
Leo makes a good point of mentioning the work with LPFML and OSiL, which
is<br>
intended to eventually render it unnecessary to write a separate driver
for<br>
every modeling-language/solver pair. I don't think that this will
be complete<br>
within the next 6 months, however.<br>
