annotate netinstall/find.cc @ 2417:8b907450718f

[xemacs-hg @ 2004-12-05 08:48:12 by ben] The section on Troubleshooting (now 2.3) has been completely written and includes a lot of stuff that is not properly documented anywhere else. A fair amount of obsolete info has been deleted and I've incorporated the comments that people (mostly Stephen T) made. Former chapter 3 has been split up in two, one pertaining to basic I/O and the other to external I/O. What were formerly chapters 5 and 6 no longer exist as such; the info in them has been distributed across various other chapters. Old chapter 4 got split up, part going to the new chapter 4 on external I/O and part going to the new chapter 5 on the Internet. In this new chapter, stuff not pertaining to a specific package (e.g. VM or GNUS) was taken out of package-specific sections and a general mail section was constituted. Part of old chapter 5 remains in a new chapter 6 devoted to Emacs Lisp and other advanced stuff, and a section from old chapter 3 on basic init-file Lisp and some stuff from old chapter 5 on Info. The rest of chapter 5 was just misc and has gotten scattered to the winds (mostly in chapters 3 and 4). Old chapter 6 has also gotten quite scattered; there is no longer any section specifically devoted to Windows except one of the Installation sections (along with a section specfically devoted to Unix), and the rest has moved to join the appropriate non-Windows-specific section elsewhere. A lot of chapters had their sections rearranged and likewise for sections having entries rearranged, with the intention that the new arrangement should be more natural. In general I hope that stuff should be much easier to locate. I also rewrote the entries on the relation between XEmacs and GNU Emacs on the authors of XEmacs, including lots of info on who wrote specific subsections. However, this history is certainly not complete; I hope people will look over this and fix it up as necessary.
