List of options to pass to the TeX compiler. It should be a quoted string of white space delimited options. Note that we always add `-interaction nonstopmode` on top of these options.

--debug,  -d

Run in debug mode. Do not clean the generated `.chk` file.

--quiet,  -q

Run in quiet mode. Do not print the output of the TeX compiler.
