I have made a new release of hfsutils, version 1.17b.
Besides a few bug fixes and code/documentation cleanups, this version also includes a working `hattrib' command-line program to change the attributes of HFS files (type/creator codes, plus the invisible/locked flags.) See the included hattrib(1) man page for details.
For completeness, the previously posted Perl script to display the partitions on a raw Apple-partitioned disk is also included in the distribution in the file "hdisk.pl". (It is not formally a part of the distribution yet, so it won't be installed by `make install'.)
The release is available here:

Also, the official home page for hfsutils is here:

Cheers,
