*** 72,78 ****
  \begin{funcdesc}{count}{\optional{n}}
    Make an iterator that returns consecutive integers starting with \var{n}.
!   Often used as a argument to \function{imap()} to generate consecutive
!   data points.  Also, used in \function{izip()} to add sequence numbers.
!   Equivalent to:

  \begin{funcdesc}{count}{\optional{n}}
    Make an iterator that returns consecutive integers starting with \var{n}.
!   Does not currently support python long integers.  Often used as an
!   argument to \function{imap()} to generate consecutive data points.

  \begin{funcdesc}{dropwhile}{predicate, iterable}
    Make an iterator that drops elements from the iterable as long as
!   the predicate is true; afterwards, returns every element.

--- 87,93 ----
  \begin{funcdesc}{dropwhile}{predicate, iterable}
    Make an iterator that drops elements from the iterable as long as
!   the predicate is true; afterwards, returns every element.  Note,
!   the iterator does not produce \emph{any} output until the predicate
!   is true, so it may have a lengthy start-up time.  Equivalent to:
  
    \begin{verbatim}

*** 105,111 ****
  \begin{funcdesc}{ifilter}{predicate, iterable \optional{, invert}}
    Make an iterator that filters elements from iterable returning only
!   those for which the predicate function evaluates to \code{True}.  If
    \var{invert} is \code{True}, then reverse the process and pass through
!   only those elements for which the function evaluates to \code{False}.
    If \var{predicate} is \code{None}, return the items that are true
    (or false if \var{invert} has been set).  Equivalent to:

! As a further example of how itertools can be combined, here
! are a few ways to define higher level tools:

  \end{verbatim}
  
! This section has further examples of how itertools can be combined.
! Note that \function{enumerate()} and \method{iteritems()} already
! have highly efficient implementations in Python.  They are only
! included here to illustrate how higher level tools can be created
! from building blocks.
