Thank you Stephen, ctm(1) is quite rad, but I see now how it doesn't = really replace the 'one-liner' pull of c[v]sup=85 I updated the wiki page with an example from your notes, https://wiki.freebsd.org/UsersFetchingSource -- With that, 2 questions: - I'm wondering if there is a clean/reliable way to pull an index of the = CTM deltas? (This is still very far from the one-liner c[v]sup had = become, it would be great to check for new delta files in a simple = automated manner.) - does CTM go away with the CVS servers, e.g. who/how is it supported = supported and maintained going foreword under SVN? Best, .ike
