Xbin is a port of the ancient Un*x tool for extracting BinHex files, based on source originally written by Dave Johnson, Brown University Computer Science.
This version is BeOS "friendly", setting the resource and filetype attributes in a fashion compliant with the HFS file system add-on. That is to say, mimetypes containing usually upper-case letters. No, this is not a good thing, but until the HFS add-on changes, it's the right thing.

What is BinHex? BinHex is an encoding scheme, now a file format, similar to uuencoding or base64. It's a plain text format, in 7-bit ASCII, but unlike uuencoding, it stores a Macintosh file's resource and data forks and Finder flags. Some downloadable files are made available in BinHex (.hqx) format, thus the possible need for this utility.
