 The templates are defined in a Lisp data file configured by ~tempel-path~. Lisp
 data files are files containing Lisp s-expressions (see ~lisp-data-mode~). By

-major mode with an optional ~:when~ condition. Each template is a list in the
-concise form of the Emacs Tempo syntax. The first element of each list is the
-name of the template. I recommend to use avoid special letters for the template
-names, since special letters may carry meaning during completion filtering and
-as such make it harder to select the desired template. Thus the name =lett= is
-better than =let*=. Behind the name, the Tempo syntax elements follow.

 In addition, each template may specify a =:pre= and/or =:post= key with a FORM that
 is evaluated before the template is expanded or after it is finalized,
