* make
* ./links -g

Works! (tested X, Framebuffer, and text modes)

* Convert icon to PNG: convert links-48x48.xpm links.png

* split into links-full.tcz, links-doc.tcz based on files included in earlier extensions.
 - mkdir -p ~/src/links_ext/2.27/links-full
 - cd ~/src/links_ext/2.27/links-full
 - for dir in `sed 's/\/[^/]*$//g' ../../links-full.tcz.list | uniq`; do sudo mkdir -p "$dir"; done
 - for file in `cat ../../links-full.tcz.list`; do sudo mv /tmp/links/"$file" "$file"; done
 - Note files not found.
 -- Repeat for links-doc
 - tree -ap /tmp/links
 - move remailing files to appropriate locations (files not found earlier are a hint)
 - cd /tmp/links
 -find -type f
  - Finds any files missed.
 - cd .. 
 - sudo rm -R links
 - cd ~/src/links_ext/2.27/
 - sudo chown -R root:root *

* Generate file lists:
  for dir in `find -maxdepth 1 -mindepth 1 -type d`; do cd $dir; find usr ! -type d | sed "s/^/\//g" > ../$dir.tcz.list; cd ..; done
* tce-load -i squashfs-tools
* Generate extensions and checksums:
* for dir in `find -maxdepth 1 -mindepth 1 -type d`; do mksquashfs $dir ${dir#./}.tcz; md5sum ${dir#./}.tcz > ${dir#./}.tcz.md5.txt; done

* Make links-full.tcz.dep based on 'ldd links-full/usr/local/bin/links':

* Copy links-full.tcz (+ dep, md5) to "tce/optional".
* tce-load -i links-full
* links -g &

works!
