+- **raw text mode**: `-t <TEXT>` or `-t "<TEXT>"` (for those including space/tabs); `-t` can be omitted as this is the default mode.
+- **output path**: `-o PATH/TO/SVG`. Automatically append `.svg` suffix if absent. When whole option is absent, use input text but path-incompatible characters substituted with `_`, and filename capped at 32 chars.
+- **batch mode**: `-i <FILE_OF_LINES_TO_CONVERT>` ; output automatically dumps generated svgs per line of input file under `output/`; SVG files named after input lines verbatim except that path-incompatible characters substituted with `_` (underbar), and filename capped at 32 chars. Disregard `-o`.
