The Heirloom Toolchest is a collection of standard Unix utilities. Highlights
are:
* Derived from original Unix material released as open source by Caldera.
* Up to four versions of each utility corresponding to SVID3/SVR4,
 SVID4/SVR4.2, POSIX.2/SUSV2, and 4BSD (SVR4 /usr/ucb).
* Support for lines of arbitrary length and in many cases binary input data.
* Support for multibyte character sets, especially UTF-8.
* More than 100 individual utilities including bc, cpio, diff, ed, file,
 find, grep, man, nawk, oawk, pax, ps, sed, sort, spell, and tar.
* The cpio and pax utilities can read and write zip files, GNU tar files,
 and the cpio formats of several commercial Unix systems.
* Extensive documentation including a manual page for any utility.
