Alternate biterscripting script.

# Script category.txt
var str rss ; cat "file.rss" > $rss
while ( { sen -r -c "^^" $rss } > 0 )
do
    var str category ; stex -r -c "^<category&\>&</category\>^" $rss >
$category
    stex -r -c "^<category&\>^]" $category > null ; stex -r -c "[^</
category\>^" $category > null
    echo $category
done
