+In order to submit a subdirectory, you may simply include a tarball. As long as
+the total size of your submission does not exceed the size limit, defined in
+[limit_ioccc.h](https://github.com/ioccc-src/mkiocccentry/blob/master/soup/limit_ioccc.h)
+as `MAX_TARBALL_LEN` and your total number of files in your xz compressed
+tarball does not exceed the limit, defined as `MAX_FILE_COUNT` in
+[limit_ioccc.h](https://github.com/ioccc-src/mkiocccentry/blob/master/soup/limit_ioccc.h),
+you can include tarballs with subdirectories or other files.
