The control file is the main input file, which can also serve to document a calculation.
Data is read from the control file by categories, one category at a time.
Apart from a mild exception described later, the order of tokens within a category is also irrelevant. Furthermore, if lm.run ran successfully then the new potential parameters, the moments, the Fermi energy and the muffin-tin zero is written in the CTRL file. A complete list of categories and an explanation of each token is given below.
