removed duplicated includes

i used the following script
(i have no awk-skills :-/ i guess with awk it will look much better)
for i in `ls *.h`
do
    HEADER="#include \\\""`echo $i | sed 's/\./\\\\./'`"\\\"" #a grep-readable #include "file.h"
    # following should deletes the first occurence of a duplicated
    # (#include) line
    # if an include is more then once in this file this script
    # has to be run more often - i don't know a better solution
    grep -cH "$HEADER" *.[hcpp]* | grep -v :1$ | grep -v :0 | sed -r 's/:[0-9]*$//' | xargs sed -i '0,/#include "'$i'"/{//d;}'
done
