     @cindex branch (version control)
     
       One use of version control is to support multiple independent lines
   ! of development, which are called @dfn{branches}.  Branches are used
   ! for maintaining separate ``stable'' and ``development'' versions of a
   ! program, and for developing unrelated features in isolation from one
   ! another.
     
       VC's support for branch operations is currently fairly limited.  For

     @cindex branch (version control)
     
       One use of version control is to support multiple independent lines
   ! of development, which are called @dfn{branches}.  Branches allow for
   ! parts of software to be developed in parallel.  Large projects require
   ! many roles to be filled, including developers, build managers, and
   ! quality assurance personnel. Further, multiple releases on different
   ! operating system platforms may have to be maintained.  Branches allow
   ! contributors to isolate changes without destabilizing the codebase,
   ! for example, fixes for bugs, new features, and versions
   ! integration. These changes may be later merged (resynchronized) after
   ! testing.

Please just remove it, since (IMO) the Emacs manual does not need to
explain every possible reason why people might want to use branches.
