@@@ -32,7 -32,7 +32,7 @@@ A typical use sets up the progress bar 
  calls L<update|"update"> to update the bar whenever an item is processed.
  
  Often, this would involve updating the progress bar many times with no
- user-visible change.  To avoid uneccessary work, the update method returns a
+ user-visible change.  To avoid unnecessary work, the update method returns a
  value, being the update value at which the user will next see a change.  By
  only calling update when the current value exceeds the next update value, the
  call overhead is reduced.

 +Sometimes we can't correctly determine the terminal width. You can use this
 +parameter to force a term width of a particular size. Use a positive integer,
 +please :)

 +=item silent
 +
 +If passed a true value, Term::ProgressBar will do nothing at all. Useful in
 +scripts where the progress bar is optional (or just plain doesn't work due to
 +issues with modules it relies on).
 +
 +Instead, tell the constructor you want it to be silent and you don't need to
 +change the rest of your program:
