+# it is then zero and not one.

+# whitespace (but not the newline character at the end of the line) is treated
+# as part of the field value. the lines will be joined with a newline between
+# them.
+#
+# 4. When the same field name appears it replaces the previous one.
+# 
+# 5. Line separator is LF and not CR LF. The CR character is treated as part of
+# the field value.
+#
+# 6. After the end of header (double newline) all next lines are treated as the
+# value of the "content" field.
