12 Downloads all of the beatmaps in your current osu! folder.
13 Consequently, can also be used to create a text file with all the beatmap id's in your /Songs folder, and/or be used to download all of the beatmap id's in a specified text file.
14
15 -h, --help show this help text
16 -g, --generate FILENAME generate beatmap id's text file
17 The default beatmap id's text file is named songids.txt and it is created into your /Songs folder. If you wish to create a file with a different name, specify the name here.
18 -d, --download [path/to/beatmap-id-file] download beatmaps from the beatmap id's text file (the default is located in your /Songs folder and that is where the program will look for the text file)
19 If you changed the beatmap id's filename then specify the new name.
20 -T, --test test if everything is working correctly; will only download the first beatmap id in the beatmap id's text file
