config files associate a property name with a value.
// comments can start at the beginning of a line
# comments can start at the beginning of a line
name: short values fit onto one line
name: a really long value that
continues on the next line
property names are case insensitive and should be less than
60 characters in length and must start at the begining of
the line, as whitespace at the start of a line signifies a
line continuation.
