- Internationalization
    - Improve: do not translate individual machine id
    - Re-use existing phrases
- Consistent punctuation and spacing

- Users of clusterstatus.pl need to have a role in one of the domain(s) to which the server where the script is being run belongs.
- Only display "Reroute to" if there are servers to which rerouting can occur.

- Changes resulting from movement of subroutines from loncgi.pm
  to lonauthcgi.pm.

- Localization
- Use routines from &Apache::lonnet() to access information about hosts etc.
  instead of reading /home/httpd/lonTabs/hosts.tab file on disk
- Two modes of use:
  (a) if called by superuser - retrieve information about servers in cluster
  (b) if called by domain coordinator - retrieve information about servers in
      domain of DC role
- Replace use of Apache Basic Auth with routines from LONCAPA:loncgi to control access
- Same routines used by pages accessed via LWP requests when compiling status information
- Correct some typos.

- up the floor on the clusterstatus page

Provide links to reroute scripts

Detects re-routing

- adding more GPL headers

Better color contrast between "local_error" and "con_lost"

Read additional fields in domain.tab

Link to announcements - they might say why the thing is down.

Smaller output, quicker building of connection matrix.

* per Guy's suggestion, change order of display versus further tests, now
  almost always displaying something
* use strict
* reduce number of bytes sent to browser (eliminating unused hidden vars)
* keep stats

Bug #1968: version information more easily available

* Making timeout even smaller. If 10 secs are not enough, there is some
trouble - which is the thing we want to detect
* Always deal with 5 connections - makes no difference in the beginning,
but makes sure that the final obnoxious holes get filed up towards the
end
* Make diagonal (connections to self) better visible in connections matrix

Speed up display by better distribution of non-cached queries, and lowering
timeout values.

Needs server name to work.

Bug #797: seems to work.

Starts to do reasonable stuff.

Bug #797: Can now list by doomedness

Saving my work: comprehensive clusterstatus

Bug #1267 - list of active users via /cgi-bin/userstatus.pl
Trying to get clusterstatus.pl working again. Added ability to ignore
comments in hosts.tab, and took out Net::Ping because that library is kaputt.

best wishes to all.

Avoid bug #429. Subroutine "online" short-circuit until we have figured out
Net::Ping.

remove access.conf; loncapa.conf is read and BY DEFAULT loncapa_apache.conf
is always read (AT THE END)

Using LONCAPA::Configuration::read_conf
BUG 129

New Cluster Status Functionality

Cluster Status Script
