mimencode
(Originally distributed as "mmencode"). A replacement for uuencode for use in electronic mail and news. Part of MIME. uuencode uses characters that don"t translate well across all mail gateways (particularly those which convert between ASCII and EBCDIC). Also, different variants of uuencode encode data in different and incompatible ways, with no standard. Finally, few uuencode variants work well in a pipe. Mimencode implements the encodings which were defined for MIME as uuencode replacements, and should be considerably more robust for e-mail use. Written by Nathaniel S. Borenstein of Bell Communications Research, Inc. (Bellcore) in 1991.
