Examples of MArgs

de.mhus.lib.MArgs
The class is a parser for program argument lists, like you get in the main(args) method. You can also put a usage definition to the constructor to define the possible methods. The parser will parse all arguments. If a minus is the first character the next argument will be stored under this key. A argument key can be there multiple times. If there no value after the key the key is marked as existing. A value without a key on front of it is stored under the DEFAUTL key. The "usage" feature is not finished yet! @author mhu
