module System.Environment.SetEnv

-- | The <a>setEnv</a> function inserts or resets the environment variable
--   name in the current environment list. If the variable <tt>name</tt>
--   does not exist in the list, it is inserted with the given value. If
--   the variable does exist, the argument <tt>overwrite</tt> is tested; if
--   <tt>overwrite</tt> is <tt>False</tt>, the variable is not reset,
--   otherwise it is reset to the given value.
