Here is my first attempt. The wording is awful, but I hope it shows
the general direction that I meant. Writing documentation is quite
hard!
If the direction is okay, I'll sleep over it and try to come up with
something more coherent.
Should there be a special `overview' section?
Should the overview come before or after the list of keys?
(Note that TAB in fundamental mode and text mode now runs
indent-relative, the following patch reflects that. Not sure if the
remark about TAB in indented text mode in the following node needs to
be changed.)
(Regarding the list of keys the node Indentation, I think that `do
like TAB on each line' is a better description of indent-region. Most
of the time, it does NOT indent all of the lines to the same column ;-)

+ Emacs supports four general categories of operations that could all
+be called `indentation':
+
address@hidden
address@hidden
+The most simple operation is to just insert a tab character. This
+operation does not have a convenient key binding, because it is
+subsumed by the more general operation described next. But you can use
address@hidden @key{TAB}} to insert a literal tab character.
+
+A tab character is displayed as a stretch of whitespace which extends
+to the next display tab stop position, and the default width of a tab
+stop is eight. @xref{Display Custom}, for more details.
+
address@hidden
+Emacs also supports tab stops. You can set them at arbitrary
+positions, and then use @kbd{M-i} to advance to the next tab stop. The
+default tab stop list contains positions (columns) that are a multiple
+of eight, and so the effect of @kbd{M-i} is the same as that of
address@hidden @key{TAB}} in the default case.
+
+You can set the tab stops with @kbd{M-x edit-tab-stops}.
+
address@hidden
+You can align successive lines with each other. This is called
address@hidden indentation} in Emacs and is performed by the command
address@hidden indent-relative}. The effect is best shown by an example:
address@hidden
+This shows the effect of relative indentation.
+^ ^ ^ ^ ^ ^ ^
address@hidden example
+The positions for the @code{^} characters on the second line were
+obtained using @kbd{M-x indent-relative}.
+
+In Fundamental mode and in Text mode, @key{TAB} runs the command
address@hidden
+
address@hidden
+The most sophisticated method is called @dfn{syntax-driven indentation}
+and is the default behavior of the @key{TAB} key in Emacs.

Most programming languages have some indentation convention. For Lisp
code, lines are indented according to their nesting in parentheses. The
same general idea is used for C code, though many details are different.
+ For some languages, different kinds of indentation styles are
+commonly used. Emacs accomodates this by allowing users to customize
+the indentation. For example, see @ref{Customizing Indentation,,,ccmode},
+for a description of these facilities for the C language.
