+ 
+ In this minor mode, a word boundary occurs immediately before an
+ uppercase letter in a symbol.  This is in addition to all the normal
+ boundaries given by the syntax and category tables.  There is no
+ restriction to ASCII.
+ 
+ E.g. the beginning of words in the following identifier are as marked:
+ 
+   capitalizedWorDD
+   ^          ^  ^^
+ 
+ Note that these word boundaries only apply for word motion and
+ marking commands such as \\[forward-word].  This mode does not affect word
+ boundaries in found by regexp matching (`\\>', `\\w' &c).
+ 
+ This style of identifiers is common in environments like Java ones,
+ where underscores aren't trendy enough.  Capitalization rules are
+ sometimes part of the language, e.g. Haskell, which may encourage such
+ a style.  It is appropriate to add `capitalized-words-mode' to the
+ mode hook for programming langauge modes in which you encounter such
+ variables, e.g. `java-mode-hook', since it's unlikely to cause trouble
+ if such identifiers aren't used.
+ 
+ See also `glasses-mode' and `studlify-word'.
+ Obsoletes `c-forward-into-nomenclature'."
