14 | # February 2018 - Anne Philipp (University of Vienna): |
---|
15 | # - applied PEP8 style guide |
---|
16 | # - added documentation |
---|
17 | # - applied some minor modifications in programming style/structure |
---|
18 | # - changed name of class Control to ControlFile for more |
---|
19 | # self-explanation naming |
---|
20 | # - outsource of class ControlFile |

31 | # from the MARS archive for driving FLEXPART are set in a CONTROL file. |
