This command will add \e{gflag} to the global define list. This will have a similar effect as using the /D switch on the command line (the define only becomes effective after the !define command).
If \e{/date} or \e{/utcdate} are used, \e{value} will be passed into strftime and the result will be used as the value of \e{gflag}. strftime converts special symbols into certain parts of the current time or date. For example, %H will be converted into the current hour in 24-hour format. For a complete list of available symbols, search for strftime on \W{http://msdn.microsoft.com/}{MSDN}. On POSIX, you can get the list by using \c{man strftime}.

This command, when paired with an !endif command, will tell the compiler whether or not to compile the lines in between the two lines. If value is non-zero, or the comparison of value and value2 depending on the operator results in true, the contained lines will be compiled. Otherwise, they will be skipped.
op can be either == or != (case-insensitive string comparison), S== or S!= (case-sensitive string comparison), =, <>, <=, <, > or >= (int/hex/float comparison), & (bitwise AND comparison), && or || (boolean comparison).
If [!] is set, return value will be switched from true to false and vice versa.
If [!] is set, the result will be flipped from true to false and vice versa.
