CrySPY uses the configparser
module to read input file,
cryspy.in consists of sections, led by a
[section] header and followed by
name = value or
name : value entries.
Section names and values are case sensitive, but names are not.
Lines beginning with
; are ignored and may be used to provide comments.
Accepted bool values are
on, which cause this method to return
off, which cause it to return
These string values for bool are checked in a case-insensitive manner.
Some values are given in a space-separated manner.
See configparser in detail.
