It is released on Internet in the info-mac archives.

What UUCD can do

• uuencode data files (resource fork and file infos are ignored)
• uudecode single or multipart files - no editing required
• uucd also works as a "droplet" for uudecoding
• the Drag Manager is supported for uudecoding
• uuencoded input sections can come from different files
• uuencoded input sections can be rearranged visually
• uudecoded output files Type and Creator automatically set (configurable)
• split the output file during uuencoding
• Binhex and MIME/Base64 support

uucd is highly System-7 dependant, but can work without ColorQD.

When you're reading news on the Net, you're likely to encounter
messages that contain lines like this:

This is a file, named 'foobar.jpg', uuencoded so that it could be sent
as text message(s), in one part or several ones, in different messages.

To decode these files, you first have to save the messages, into one or
several files, it doesn't matter. All you have to do next is to drag and
drop your message files on the uucd application icon (or open them
from uucd's file menu, but it can be much longer if you have many files).

As the message files are loading, each segment of uucode shows up
as an icon with some textual info on the right. When some consecutive
segments seem to form together a file (the first segment shows up
as a 'begin' icon, the last one as a 'end' icon), the icons of this stream
of segments are changing to outlined ones, with a 'save' mini-icon
at the left of the 'begin' icon. Then you can save the file by clicking
on this 'save' mini-icon.

If the segments are in a wrong order, you can rearrange it by 'drag
and drop' on every misplaced segment. The textual infos at the right
of the segment icons are here to help you to identify the segments.
A first column shows the destination filename associated with a
'begin' segment. The second one gives the last 'Subject:' encountered
while processing the messages. If there is no subject line then the
source file name is used, eventually followed by a number.

The 'Sort' button can help you to rearrange automatically the segments
in the proper order. It is designed to work as well as possible in most
simple cases, no more.

When Binhex files are encountered, they are loaded but saved only
in their .hqx text form. uucd then only works as a merging tool.
You can use StuffIt Expander or other Binhex decoders to decode
the .hqx file.

When MIME/Base64 files are encountered, they are fully decoded.
uucd also tries to guess the file name from the last subject line.
I couldn't find a good, real documentation about this format, and
there seems to be several idioms of it. I can only say that it worked
quite well these last days, on some f*%/=ng base64 posts found
in the news.

Troubleshooting

• uucd doesn't recognize any line of an uuencoded file

Are you sure that it's uucode? Some email programs send
attachments in other formats. uucd may not handle them.

• uucd can't decode MIME/base64 lines

Oh, well, maybe uucd isn't so perfect. You can try MPack
(available by anonymous ftp to ftp.andrew.cmu.edu, directory
/pub/mpack).

• uucd reads my uucode files, but I don't get any uudecoded one

Uh... ok, uucd has read the uucode and converted it to binary
segments, but you didn't even try to save them, didn't you ?!
Try the 'Save All' button at the bottom of the window, or the
little disk icon at the topleft of each complete list of segments.

• You get a 'The application's free memory seems to get low' alert

uucd uses the application's memory to  store the uudecoded segments.
When trying to decode large files, there may be insufficient memory
allowed to uucd.

To change it, quit uucd, select the application's icon from the
Finder and ask 'Get Info' from the 'File' menu. There you can
change the amount of memory available to uucd.

Disclaimer

#include <stddisclaimer.h>
/* use it at your own risks, blah blah... */

I wrote uucd to suit my personal needs.

There are many other uudecoders for the Mac, uucd simply does
everything I've always wanted the others to do, no more.
So if uucd doesn't suit your needs, you can email me or try
another decoder.
