content/en: Use <<section>> for linking within a document
I've used the following script to locate all the cases where crossref
was used to link to a section within the same document:
grep -R crossref: | while read -r case; do
file=${case%%:*}
dir=${file%/*}
dir_name=${dir##*/}
line=${case##*:}
target_document=${line%%[*}
if [ "$dir_name" = "$target_document" ]; then
echo "$case"
fi
done
