   4 /* This file contains all the flags used in the aClient and Player classes.
   5  * More flags can be added simply by going up in multiples of 2.
   6  * ie. 0001 0002 0004 0008 0010 0020 0040 0080 0100 0200 0400 0800 1000 2000 4000
   7  *     8000 10000 20000 40000 80000 100000 200000 400000 800000 1000000 2000000 4000000
   8  *     8000000 10000000 20000000 40000000 80000000 (32 bit)
   9  * This method was taken from my experience in working with various
  10  * IRCD packages. Most of them use this for their modes along with
  11  * corresponding letter representations.
  12  * Theoretically, each flag is 32 bit (long int), and each place in a flag
  13  * is one hexadecimal digit (four bits). So, technically each flag variable
  14  * can hold 8 spaces for flags. 8 spaces at 4 flags per space makes for
  15  * 32 possible flags for each long int. That means there are 32 flags available
  16  * for the aClient class, and 32 for the player class.
  17  *
  18  * Basically if you are having problems visualizing how flags work, think of them in
  19  * binary terms:
  20  *      Hex     Binary
  21  *      0x0001  0001
  22  *      0x0002  0010
  23  *      0x0004  0100
  24  *      0x0008  1000
  25  *     Basically, each flag represents a 1. When you add the different flags, you are just
  26  *      adding a 1 in the given position. So 1001 would be 0x0009 or flags 0001 and 0008.
