/* Who & Where statistic generator for Oops log files Make it with 'gcc -o waw waw.c'. Should compile without errors. Run it with './waw -h' to get help on usage. Note: It's my first attempt in C. It's probably buggy, unstable, badly structured and using strange and/or non-standard methods of doing things. Nevertheless it works for me. :-) And again I just learn C coding this. Have patience.
