MususUmbra/Huffman/Huff_txt
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

File contents
Huff
~~~~
Huff is a simple non-adaptive huffman en/decoder. It is supplied here so
that those who wish to may (de)compress the Automine sprites and edit them.
Please note that you must not distribute such modified files - if you want
to share your new sprites, you must extract them into (a) standalone
spritefile(s) and distribute only your work (with some instructions as to
how to install them :)
Huffman encoding is lossless in nature, but less efficient than (say) LZW
compression. Where Huffman encoding scores over LZW is that is requires
only a small fraction of the memory to compress/decompress a set of data -
hence its use in Automine.
The huff utility preserves filetype, datestamp, etc. (much as Squash does).
Encoded files are given the filetype EA4 which is unofficial (and indeed
lies in the 'generic data types' range), but I'm not aware of any
clashes. Automine uses the filetype of the sprite files to decide whether
to load then using huffman decoding, or just as plain sprites.
The two sprite files supplied are high- and low- resolution file icons for
huffman encoded data.
Use
~~~
huff compresses from one file to another. If two files are specified on
teh command line, then the must not be the same. If only one is specified,
huff will automatically substitute a scrapfile for the <outfile> and then
replace the <infile> with the scrapfile if successful.
The syntax is:
huff [-v[v]] [-d] <infile> [<outfile>]]
The options are:
-v : verbose mode. Progress reports are printed, along with
some statistics.
-vv : super-verbose mode. As -v, but additionally the character
frequencies, encoding tree and bit patters are displayed.
-d : decode (decompress). The default action is to encode.
So, to compress the file 'Foo' saving the output as 'Foo-h', you could use:
huff -v Foo Foo-h
And to decompress 'Foo-h' as 'Foo':
huff -d -v Foo-h Foo
If you specify the <outfile> as '-', output will be written to vdu:. This
is only provided so that encoded text files may be *type-d using huff.
If the <infile> is not suitable for the operation requested, an error message
is printed, but the program terminates 'successfully', eg. it won't stop
an Obey file processing.
A file is suitable for encoding if it isn't already encoded (ie. its filetype
isn't &EA4 and its first four characters aren't "HUFF"). A file is suitable
for decoding if its filetype is &EA4 and its first four bytes are "HUFF".
