Master List Package Dependencies For PHP 5/6

Hi All, There have been a number of recent threads on upgrading PEAR to better support PHP 5/6. If packages were all isolated then upgrading would be straight forward but there are of course many inter-dependencies. Some folks have mentioned that there are about 20 packages that are heavily depended on. Seems to me that it might be nice to know exactly what might be involved in upgrading a package from a dependency point of view. If we had a master list of all packages and their dependencies then perhaps we could pull this into a spreadsheet or database and do some some slicing and dicing. Determine which packages really are depended heavily on. Maybe come up with an overall strategy of which packages should be upgraded first. That sort of thing. Maybe this capability already exists? If not, I assume it's a question of reading through the package files and pulling out the data? A master list might be useful for other things as well. Art
