How to generate an ISO bootable image from a bootable CD?

Hello,
I'm trying to use the Solaris tools to generate an ISO bootable image from a bootable CD.

I'm having a hard time partially because the traditional tools seems to be changing.
For example, there's no isoinfo, hexdump or isodump anymore, only xorriso which is nearly impossible to use.

Can you help or point to some high-level and useful how-to?
For example, where I find specific command lines for:

     Overview of features:
     Operates on an existing ISO image or creates a new one.
     Copies files from disk filesystem into the ISO image.
     Copies  files  from  ISO  image  to  disk  filesystem   (see osirrox).
