\c [!] /FileExists "c:\path\file.exe"
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 != (string comparison), <=, < > or >= (float comparison), & (bitwise AND comparison), && or || (boolean comparison).
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.
