Code:
system( q@awk -F',' 'FNR==NR {buff[$1]=$0;next}
                  {
                     if(buff[$1]=="") { new[$1]=$0; next;}
                     if(buff[$1]==$0) { delete buff[$1]; next;}
                     if(buff[$1]!=$0) { chng[$1]=$0; delete buff[$1];}
                  }
                  END{

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
