a lot of perl -pi.bkp -e andfind with -exec was involved in munging the large number of file:/// URLs into relative URLs to get from what I started with to what I pushed to github. Some time after the v10 dust has settled, I’m going to sit down and redesign inf7, which generated the HTML of the Project Index and the docs, for v10. (I am using it with v10 today, but via some seriously ugly hacks. And I had mistakenly thought the Index format was so close to unchanged in v10 it would still work, but no.)
Currently in v10 the index module hard-codes HTML output. It would be cool if maybe someday there were formatting-agnostic plain-data output and then, by default, inweb could transform that into the Project Index as the IDEs expect it.
