Write a lex program which will read web logs from stdin and write to stdout a version of the log with tab characters seperating the fields. Spaces within fields must be preserved. You may assume that every field in the input that contains spaces is enclosed in double quotes, except for the timestamp which is enclosed in square brackets. Also no field begins with or ends with a space but may conain embedded double quoted preceded by backslashes. Create a hell script named soln02 that will run the lex program.
