NAME
      uuencode, uudecode - encode a binary file, or decode its ASCII
      representation

SYNOPSIS
      uuencode [ source-file ] file-label

      uudecode [ encoded-file ]

DESCRIPTION
      uuencode converts a binary file into an ASCII-encoded representation that
      can be sent using mail(1).  It encodes the contents of source-file, or
      the standard input if no source-file argument is given.  The file-label
      argument is required.  It is included in the encoded file's header as the
      name of the file into which uudecode is to place the binary (decoded)
      data.  uuencode also includes the ownership and permission modes of
      source-file, so that file-label is recreated with those same ownership
      and permission modes.

      uudecode reads an encoded-file, strips off any leading and trailing lines
      added by mailer programs, and recreates the original binary data with the
      filename and the mode and owner specified in the header.

      The encoded file is an ordinary ASCII text file; it can be edited by any
      text editor.  But it is best only to change the mode or file-label in the
      header to avoid corrupting the decoded binary.

NOTES
      The encoded file's size is expanded by 35% (3 bytes become 4, plus
      control information), causing it to take longer to transmit than the
      equivalent binary.

      The user on the remote system who is invoking uudecode (typically uucp)
      must have write permission on the file specified in the file-label.

      Since both uuencode and uudecode run with user ID set to uucp, uudecode
      can fail with permission denied when attempted in a directory that does
      not have write permission allowed for other.
