## Summary:

  This library offers two functions that perform schema validation.
  Use this is your Elisp packages to provide very informative error
  messages when your users accidentally misconfigure a variable.
  For instance, if everything is fine, these do the same thing:

    1.  (validate-variable 'cider-known-endpoints)
    2.  cider-known-endpoints

  However, if the user has misconfigured this variable, option
  1. will immediately give them an informative error message, while
  option 2. won't say anything and will lead to confusing errors down
  the line.

  The format and language of the schemas is the same one used in the
  `:type' property of a `defcustom'.
