+"""Load / save to libwww-perl (LWP) format files.
+
+Actually, the format is slightly extended from that used by LWP's
+(libwww-perl's) HTTP::Cookies, to avoid losing some RFC 2965 information
+not recorded by LWP.
+
+It uses the version string "2.0", though really there isn't an LWP Cookies
+2.0 format.  This indicates that there is extra information in here
+(domain_dot and port_spec) while still being compatible with libwww-perl,
+I hope.
