   The \thmtools bundle is a collection of packages that is designed to
   provide an easier interface to theorems, and to facilitate some more
   advanced tasks.

   If you are a first-time user and you don't think your requirements are out
   of the ordinary, browse the examples in \autoref{cha:impatient}. If you're
   here because the other packages you've tried so far just can't do what you
   want, take inspiration from \autoref{cha:extravagant}. If you're a repeat
   customer, you're most likely to be interested in the refence section in
   \autoref{cha:reference}.

   Since you most likely want to add keys as well, there is a shortcut that
   \thmtools\ offers you: whenever you use a key |key| in a
   |\declaretheorem| command, and \thmtools\ doesn't already know
   what to do with it, it will try to |\usepackage{thmdef-key}| and
   evaluate the key again. (If that doesn't work, \thmtools\ will cry
   bitterly.)
-  
+
   For example, there is no provision in \thmtools\ itself that make the
   |shaded| and |thmbox| keys described above special:
   in fact, if you want to use a different package to create frames, you just
   put a different |thmdef-shaded.sty| into a preferred texmf tree.
   Of course, if your new package doesn't offer the old keys, your old
   documents might break!
-  
+
   The behaviour for the keys in the style definition is slightly different:
   if a key is not known there, it will be used as a ``default key'' to every
   theorem that is defined using this style. For example, you can give the
   |shaded| key in a style definition.
-  
+
   Lastly, the key-val arguments to the theorem environments themselves need
   to be loaded manually, not least because inside the document it's too late
   to call |\usepackage|.
