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