Two months ago I did something similar this way:

#! /bin/awk -f
!/\tPin/ { print }
/\tPin/ {delta=600;
 if ($3+delta<$5) print; else
 print "\t"$1" "$2" "$3" "$4" "$3+delta" "$6" "$7" "$8" "$9" "$10;
}

#! /bin/awk -f
!/\tPad/ { print }
/\tPad/ {delta=600;
 if ($5+delta<$7) print; else
 print "\t"$1" "$2" "$3" "$4" "$5" "$6" "$5+delta" "$8" "$9" "$10;
}

(two scripts: for pins and for pads to set minimum mask clearance
to 3 mil (delta/2/(100 PCB units/mil))

Such things are done in a minute, they don't need any special tool.
