/usr/ports/shells/heirloom-sh/pkg/DESCR: The Heirloom Bourne Shell is a portable variant of the traditional UNIX shell. It has been derived from OpenSolaris code, thus implementing the SVR4/SVID3 level of the shell. Today, the Bourne shell is most useful for script portability testing and for the processing of legacy scripts. Although the Bourne shell is not POSIX-compliant because the POSIX.2 standard introduced requirements incompatible with existing Bourne shell behavior, it remains the ancestor of modern shell scripting languages. Most scripts that run on the Heirloom Bourne Shell will work with any shell still in use in the twenty-first century. It is relatively easy to write shell scripts that are both POSIX-compliant and usable with the Bourne shell. Some historical scripts make use of language features proprietary to the Bourne shell. In some cases, the conversion to portable shell language may be a tedious task. Running such scripts on the Heirloom Bourne Shell might be a convenient alternative.
