quadratic programming problems involving continuous or integer
variables by

Contact FICO for details on getting the XPRESS libraries
and header files.

Source file xpress.c is an AMPL driver for XPRESS.

Files makefile.u and makefile.vc are sample makefiles for Linux or
Unix systems and for Microsoft Visual C++, respectively.  Copy one of
them to "makefile" and edit the latter to have assignments to
XPRESSDIR, S, CFLAGS, etc., that are suitable for your system.

For a summary of using solver "xpress", execute

        xpress '-?'
or
	xpress -?

(depending on the syntax required by your shell).  More details
appear in README.xpress.
