Binhex - Convert Files Generated by Xbin or Macget Into BinHex Format
------------------------------------------------------------------------
SUMMARY
DETAILS
This utility converts Mac Bin Hex files (8-bit) to BinHex format (7-bit)
and is similar to uuencode. BinHex is based on a UNIX program with the
same name and function ( <http://www.natural-innovations.com/binhex/>
http://www.natural-innovations.com/binhex/).
The original tool was a series of small programs (8to6, crc, etc.) piped
together and run by a shell script. This is a completely rewrite as a C
program (speeding it up considerably, needless to say), with an added
run-length compression, and bullet-proofed (at least partly).
Source Code:
/* bin hex -- bin hex aufs files
*
* if called binhex handles aufs files, if called unxbin handles
*.{rsrc,data,info} files
* will process multiple files
*
* RoD hEDoR, rodhedor at yahoo
*
* This is a hacked version of...
*
* unxbin -- convert files generated by xbin or macget into BinHex 4.0
format.

* rod hedor, web http://lezr.com

*
* This is based on a Unix(tm) program with the same name and function
written
* by ????. Original was a series of small programs (8to6, crc, etc.)
piped
* together and run by a shell script. I completely rewrote the system as
a
* C program (speeding it up considerably, needless to say), added
run-length
* compression, and bullet-proofed (at least partly) the thing.
Unfortunately,
* I have lost the name of the original poster (to net.sources.mac) without
* whom this would never have appeared.
