AFT development has dormant for about 1 year, so I decided to reboot it with a minor (experimental) release (5.098) that supports Indexing. This is mostly useful for LaTeX output. I'm not sure how useful the HTML output will be.
I've also started to clean up the Perl source for AFT. I am currently reading the new edition of Effective Perl Programming and hope to apply more idiomatic Modern Perl conventions to the 14+ year old AFT sources.
As always, AFT is available through "sudo apt-get install aft" under Ubuntu (and Debian?). But to get this new release, go to the AFT website. (For a quick look at Indexing in action, look at the aft reference manual and scroll to the last page).
