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.
