                     53: .Nm uudecode
                     54: are used to transmit binary files over transmission mediums
                     55: that do not support other than simple
                     56: .Tn ASCII

                     61: .Ar file
                     62: (or by default the standard input) and writes an encoded version
                     63: to the standard output.
                     64: The encoding uses only printing
                     65: .Tn ASCII
                     66: characters and includes the
                     67: mode of the file and the operand
                     68: .Ar name

                     76: The resulting file is named
                     77: .Ar name
                     78: and will have the mode of the original file except that setuid
                     79: and execute bits are not retained.

                     82: .Sh EXAMPLES
                     83: The following example packages up a source tree, compresses it,
                     84: uuencodes it and mails it to a user on another system.
                     85: When
                     86: .Nm uudecode
                     87: is run on the target system, the file ``src_tree.tar.Z'' will be
                     88: created which may then be uncompressed and extracted into the original
                     89: tree.
