Format
The header line usually starts with "begin", followed by a Unix file permission code and a filename. The last line is "end".
Each line of data begins with a character indicating the line length. Since lines have a standard length, all lines except the last one begin with "M".
Base64 variant
Some uuencode utilities support a variant format that uses standard Base64 encoding, with a "begin-base64" header line, and a "====" footer line.
