Experts remain divided on how best to rein in costs. Some say the answer is greater regulation of drug prices. Others charge that excessive regulation is driving up costs. A big part of the problem, Schondelmeyer says, is that the health care market is so complex — with deductibles, hidden discounts, copays and rebates — that doctors and patients have little idea what a drug actually costs. "Until people know exactly what they're paying, it's almost impossible to make informed decisions," he says. The recent uproar over generic drug increases at least has the virtue of shining a light on how absurd some drug prices are, which could in turn add pressure for greater transparency.
GMT is an open source collection of about 80 command-line tools for manipulating geographic and Cartesian data sets (including filtering, trend fitting, gridding, projecting, etc.) and producing PostScript illustrations ranging from simple x–y plots via contour maps to artificially illuminated surfaces and 3D perspective views; the GMT supplements add another 40 more specialized and discipline-specific tools. GMT supports over 30 map projections and transformations and requires support data such as GSHHG coastlines, rivers, and political boundaries and optionally DCW country polygons. GMT is developed and maintained by Paul Wessel, Walter H. F. Smith, Remko Scharroo, Joaquim Luis and Florian Wobbe, with help from a global set of volunteers , and is supported by the National Science Foundation .
