- *      Further, you can automatically format this list for use as a struct

- *        # gcc -E -dM <file> | grep '__NR_' | \
- *          sed -e 's/#define[ \t]\+__NR_//' | sort | \
- *          sed -e 's/\([^ \t]\+\)\([ \t]\+\)\([0-9]\+\)/\t{ \"\1\", \3 },/'
- *      Finally, when creating a table/array of this structure, the final
- *      sentinel entry should be "{ NULL, __NR_SCMP_ERROR }"; see the existing
- *      tables as an example.
