[ANNOUNCEMENT] Updated: sharutils-4.7-1

Hash: SHA1

A new release of sharutils, 4.6.3-1, is available, replacing 4.6.3-1 as

This is a new stable upstream release.  It switches over to GPLv3; little
else has changed.  Using shar on text mounts continues to have the
possibility that line endings on text files might not be handled the way
you want, but if it was truly a text file, that should not matter to you;
the heuristic that shar uses to decide between text and binary files is
whether it contains non-printing characters.  It is safer to use
shar/unshar on binary mounts (remembering that unshar is inherently
unsafe).  uuencode and uudecode, on the other hand, work reliably
regardless of the underlying mount point.  Upstream changes since 4.6.3
are listed below; see also the package documentation found in

Version 4.7 - July 2007, by Bruce Korb

* fix a grammatical typo in doc/uuencode.1
* relicense the product under GPL version 3.

The sharutils package contains the GNU shar utilities, a set of tools
for encoding and decoding packages of files (in binary or text format)
in a special plain text format called shell archives (shar).  This
format can be sent through e-mail (which can be problematic for
regular binary files).  The shar utility supports a wide range of
capabilities (compressing, uuencoding, splitting long files for
multi-part mailings, providing checksums), which make it very flexible
at creating shar files.  After the files have been sent, the unshar
tool scans mail messages looking for shar files.  Unshar automatically
strips off mail headers and introductory text and then unpacks the
shar files.

Note that unshar is inherently unsafe by design, because it executes
arbitrary shell scripts; therefore the creation of shar archives should be
limited to situations where the receiver trusts the sender.  However,
uuencode and uudecode are useful in their own right, and are safe to use.
