new package: tcsh617

An new tcsh617 package that serves as a replacement for the tcsh package, and
provides a number of bug fixes and enhancements over the tcsh package, is now
available for Red Hat Enterprise Linux 5.

Tcsh is a command language interpreter compatible with the C shell (csh), which
can be used as an interactive login shell, as well as a shell script command
processor.

This new tcsh617 package serves as a replacement for the tcsh package, and
upgrades tcsh to upstream version 6.17, which incorporates a number of bug fixes
and enhancements over the previous version (6.14), which was released as a part
of Red Hat Enterprise Linux 5.5. The tcsh package has been retained for
compatibility with the older version of tcsh.

The tcsh and tcsh617 packages are mutually-exclusive: both packages cannot be
installed simultaneously. Users of tcsh who require the bug fixes and
enhancements included in this upgraded package are advised to first uninstall
the tcsh package and then install this new tcsh617 package. Space precludes
documenting all of these changes in this advisory. Users are directed to the Red
Hat Enterprise Linux 5.7 (BZ#676136)

Space precludes documenting all of these changes in this advisory. Refer to the
Red Hat Enterprise Linux 5.7 Technical Notes for information about these
changes:

All users of the tcsh package who want to upgrade their version of tcsh to 6.17
are advised to uninstall the tcsh package and then install this upgraded tcsh617
package, which provides these bug fixes and enhancements.
