The Lex Tool - Parser generator

Hi coder ! I found s parser generator that generates a " .l " file when a .c , .cpp file is given as input ...
This software is for windows and of course its a shareware version i.e.  they only offer a version that works for 30 days to the max ( thats enough for us ) and then u know the rest ...
As for me , i tested giving a .c prog input and went to Project->parserwizard and generated a " .l " file but didn understand what it contained ....
check it out ....
