• Windows does not have "rm"
• Documentation: can "chemobabelimgdir" be changed via \renewcommand ? → No! (If "chemobabelimgdir" can be changed or user-defined "Prefix" is allowed, extra hacks on LuaTeX will be required. Twitter)
• Documentation: mention GitHub in the dtx/pdf also → Done (2022-09-19)

• Syntax of \chemobabel/\smilesobabel command: some people complains about the second optional argument, so adding \chemobabel*/\smilesobabel* variant with only one argument → Done (462f9a8)
• Warn if a user need to run another latex (Note: running without -shell-escape after removing [extract] should not issue a warning) → An idea of writing the number of images by \chemobabel/\smilesobabel into .aux file, and read it on the second run to see if the number changed ? → Done in 9fea08b and 4f00bf6

• Handle options in the order they are given → Done in 667b2ef and 2dd5ed6
• Safety check of \jobname before opening ChemFigFile.tex on [extract] → Done (e448147)
• Pass the original package options into extracted ChemFigFile.tex → Done (d69604d)

[aminophen]

• Default image format EPS when the engine/driver does not support PDF, by detecting graphicx driver (e.g. latex+dvips) → Done (f934c91)

Documentations → All done (61a6786)

• Restriction: when using -output-directory, the extracted code "ChemFigFile.tex" goes there but chemobabelimgdir and generated images stay in the current directory. (Note: the .aux file goes to given output directory, but the engine reads .aux in the output directory first, so it's fine)
• A bit more documentation for default cropping, including:
  • pdfcrop or ps2eps should be found on PATH
  • \includegraphics option [clip] is useful for proper EPS cropping
• Documentation for automatic default PDF/EPS selection of f934c91 for next release

Remainings:

• Windows does not have "rm"; what is the best way of removing a file on Windows?
• Recent version(s) of "rsvg-convert" generates PDF-1.7 by default, which is higher than what TeX world expects so raises warnings:

pdfTeX warning: pdflatex (file ./chemobabelimgdir/smilesobabelimg1-crop.pdf): PDF inclusion: found PDF version <1.7>, but at most version <1.5> allowed

dvipdfmx:warning: Trying to include PDF file with version (1.7), which is newer than current output PDF setting (1.5).
