By blackosx, Revise layout of package installer 'Welcome' file so it looks cleaner. Change the copyright notice to begin from 2009 as seen in the Chameleon 2.0 r431 installer. Should this date be set earlier?

52 * same type as would an expression that is an object of the corresponding
53 * type converted according to the integral promotions. The subtraction for
54 * INT_MIN and LONG_MIN is so the value is not unsigned; 2147483648 is an
55 * unsigned int for 32-bit two's complement ANSI compilers (section 3.1.3.2).
56 * These numbers work for pcc as well. The UINT_MAX and ULONG_MAX values
57 * are written as hex so that GCC will be quiet about large integer constants.
