+         SIESTA is both a method and its computer program
+         implementation, to perform efficient electronic structure
+         calculations and ab initio molecular dynamics simulations of
+         molecules and solids. SIESTA's efficiency stems from the use
+         of strictly localized basis sets and from the implementation
+         of linear-scaling algorithms which can be applied to suitable
+         systems. A very important feature of the code is that its
+         accuracy and cost can be tuned in a wide range, from quick
+         exploratory calculations to highly accurate simulations
+         matching the quality of other approaches, such as plane-wave
+         and all-electron methods.
