      1 This package contains various C programming debugging utilities, such as:
      2 
      3 	addr2line - translates program addresses into file names and line
      4 	numbers. Given an address and an executable, it uses the debugging
      5 	information in the executable to figure out which file name and
      6 	line number are associated with a given address;
      7 
      8 	gcov - displays basic block profile / coverage data, if requested
      9 	via the C compiler gcc(1) command line options -fprofile-arcs and
     10 	-ftest-coverage. These options cause the compiler to insert
     11 	instrumentation into the object files it generates, which measure
     12 	how often each basic block is executed; 
     13 
     14 	gdb - is the GNU debugger. The purpose of a debugger such as GDB
     15 	is to allow you to see what is going on ``inside'' another program
     16 	while it executes, or what another program was doing at the moment
     17 	it crashed;
     18 
     19 	gprof - displays call graph profile data. gprof produces an
     20 	execution profile of C, Pascal, or Fortran77 programs.
