11     UUuueennccooddee and uuuuddeeccooddee are used to transmit binary files over transmission
12     mediums that do not support other than simple ASCII data.
13
14     UUuueennccooddee reads _f_i_l_e (or by default the standard input) and writes an
15     encoded version to the standard output.  The encoding uses only printing
16     ASCII characters and includes the mode of the file and the operand _n_a_m_e
17     for use by uuuuddeeccooddee.
18
19     UUuuddeeccooddee transforms _u_u_e_n_c_o_d_e_d files (or by default, the standard input)
20     into the original form.  The resulting file is named _n_a_m_e and will have
21     the mode of the original file except that setuid and execute bits are not
22     retained.  UUuuddeeccooddee ignores any leading and trailing lines.

25     The following example packages up a source tree, compresses it, uuencodes
26     it and mails it to a user on another system.  When uuuuddeeccooddee is run on the
27     target system, the file ``src_tree.tar.Z'' will be created which may then
28     be uncompressed and extracted into the original tree.

37     The encoded form of the file is expanded by 35% (3 bytes become 4 plus
38     control information).
