+lnk_path:
+    The filepath of the lnk file you want to create.
+
+target:
+    The filepath of the target file and any additional arguments separated
+    by spaces. If you want to include an argument that starts with hyphens,
+    consider putting this last and use `--` to indicate the end of named
+    arguments. For example:
+    > shortcut game.lnk --icon game.ico -- javaw.exe -jar game.jar
+
+--start-in:
+    Directory to use as CWD for the program.
+
+--icon:
+    Path to an .ico file.
