Over the last couple of days I've been working on implementing and testing a link-checking job to run on the TEI Jenkins checking links in the Guidelines. the CLI tool linkchecker seems to be the best option, so I'm testing it and building a Makefile and some XSLT to fit it into our system. All details on the tests and what I've learned is in emails to various folks in Systems who are interested in a possible replacement for Xenu.
