doc: simple .tex to .md conversion?

[paugier]

I'd need to convert 2 .tex files to MyST .md files. I searched on the web and https://mystmd.org.

I found that it seems possible with Pandoc.

I found https://www.npmjs.com/package/tex-to-myst but did not understand how to use it.

Reading, https://mystmd.org/guide/writing-in-latex#approach, it seems that it could nearly be possible but that it is not supported.

However, I tried

myst build *.tex --md

which seems to do what I want and actually much more (partly because the .tex files were in my Downloads directory containing other things):

⛔️ EcoleM1_Fargo3D.tex 'name' must be object, not array (at EcoleM1_Fargo3D.tex#frontmatter.authors.0)
⛔️ EcoleM1_FluidSim.tex 'name' must be object, not array (at EcoleM1_FluidSim.tex#frontmatter.authors.0)
📬 Performing exports:
   EcoleM1_Fargo3D.tex -> _build/exports/ecolem1-fargo3d.md
   EcoleM1_Fargo3D.tex -> _build/exports/ecolem1-fluidsim.md
⚠️  myst.yml Loading project from path with no config file: /home/pierre/Downloads
Consider running "myst init --project" in that directory

Is there a better way to do this simple conversion?
