b64 - simple but useful Base-64 encoder/decoder

There's probably nothing you can do with this that you can't do with other tools, but I've found it useful to keep around.

The default behaviour is to Base-64 encode a text (from the command-line arguments) and print the result on standard out, broken into 76-character lines. Add -d to decode Base-64 in the same mode.

If the data is binary, you can add -h to get a hex dump of the result.

To read from a file, use -f <file>, and to write the result to a file, use -o <file>.

To stop the program from breaking Base-64 output in 76-character lines, use -B.
