30! Description:
31! ------------
32! Standard kind definitions
33! wp (working precision) and iwp (integer working precision) are the kinds
34! used by default in all variable declarations.
35! By default, PALM is using wp = dp (64bit), and iwp = isp (32bit).
36! If you like to switch to other precision, then please set wp/iwp
37! appropriately by assigning other kinds below.
