From the tutorials on that page, it appears to be simply a case of curves processing on each channel separately. As IM is not interactive, you will have to play some with things like -level, +level, -sigmoidal-contrast, -gamma etc on each channel to get the effect you want.

I also have a curves script, but it does not allow direct manipulation of each channel. So one would have to separate channels, process independently with the script, then recombine the modified channels.

If you apply a complex cross-process on a "HALD" image
You can the re-apply the same process quickly to any other image

Would you care to submit your HALD image and perhaps the process you used to create it?
or perhaps you have your own website with the info :-)
