=head1 NAME

install_web_site_cronjob - maintain install.lon-capa.org web-site every day

=head1 DESCRIPTION

This is a file that runs periodically on B<install.lon-capa.org>.

This file should be run by the 'loninst' user and be part of
the 'loninst' crontab entries (to view loninst crontab, login
as loninst and crontab C<-l>; to edit loninst crontab, login as
loninst and crontab C<-e>).

This file should be on the B<install.lon-capa.org> filesystem as
F</home/loninst/auto/autotardist>.

The current 'loninst' crontab entry is:

13 16 * * *    /home/loninst/auto/autotardist

The main goal of B<autotardist> is to periodically produce the
tarball needed for LON-CAPA installation.

A secondary yet important function of B<autotardist> is that it
also refreshes the documentation present on the install.lon-capa.org
web site.

The coding of this script is a strange brew of shell commands
with perl.
