ITS4 is a  tool   that statically scans  C and   C++ source  code  forpotential security  vulnerabilities.  It is  a  command-line tool thatworks across  Unix environments (hopefully)  and will also  work underWindows.  ITS4  scans   code, looking for    function  calls that  arepotentially  dangerous.   For some calls,  ITS4 tries  to perform somecode analysis to determine how risky the call  is.  In each case, ITS4provides  a   problem report, including  a  short  description  of thepotential problem and suggestions on how to fix the code.See  the file INSTALL    for installation instructions, and  the  fileCHANGES for modifications since 1.0.
