Uuencoding is notoriously badly specified. This implementation is compatible with the GNU Sharutils (http://www.gnu.org/software/sharutils/).

Documentation
Chop up a string in parts. Each string in the resulting list is prepended with the length according to the uuencode "specificiation".
Notes:
- The length of the strings in the result will be
(n -1)
. Thediv
4 * 4 + 1-1
comes from the need to prepend the length (which explains the final+1
). Keeping it to a multiple of 4 means that strings returned fromencode
can be chopped without requiring any changes. - The length of lines in GNU's sharutils is 61.
