c3d on MacOS M3

[Michelangelo Fabbrizzi]

Dear experts,

I would need to use c3d_affine_tool on my macOS with M3, I downloaded it at https://sourceforge.net/projects/c3d/files/c3d/Nightly/c3d-nightly-MacOS-arm64.dmg/download , however I am unsure how to use it from Terminal.

I found this post https://groups.google.com/g/itksnap-users/c/pfcQ-66OXHQ/m/A66R63UD1PYJ so I was able to find the file c3d_affine_tool in Contents/bin

I would be grateful if you could clarify how I can now use it from Terminal: I cannot find any usr/local/bin folder where to paste it.

Gratefully,

Mic
