                     10: 
                     11: This is a file that runs periodically on B<install.lon-capa.org>.
                     12: 
                     13: This file should be run by the 'loninst' user and be part of
                     14: the 'loninst' crontab entries (to view loninst crontab, login
                     15: as loninst and crontab C<-l>; to edit loninst crontab, login as
                     16: loninst and crontab C<-e>).
                     17: 
                     18: This file should be on the B<install.lon-capa.org> filesystem as
1.2       harris41   19: F</home/loninst/auto/install_web_site_cronjob>.
1.1       harris41   20: 
                     21: The current 'loninst' crontab entry is:
                     22: 
1.2       harris41   23: 13 16 * * *    /home/loninst/auto/install_web_site_cronjob
1.1       harris41   24: 
1.2       harris41   25: The main goal of B<install_web_site_cronjob> is to periodically produce the
1.3       albertel   26: unstable tarball needed for LON-CAPA installation.
1.1       harris41   27: 
1.2       harris41   28: A secondary yet important function of B<install_web_site_cronjob> is that it
1.1       harris41   29: also refreshes the documentation present on the install.lon-capa.org
                     30: web site.
                     31: 
1.5       harris41   32: This documentation is refreshed based on a file located inside
                     33: F</home/loninst/public_html/versions>.  This file is named
                     34: F<LATEST-IS-VERSIONNUMBER>, where
                     35: I<VERSIONNUMBER> is the latest stable release of loncapa (e.g. 0.4 or 0.6.1).
                     36: The F<LATEST-IS-VERSIONNUMBER> file contains a string
                     37: that is used to date the release of the current stable version.
1.3       albertel   38: 
1.1       harris41   39: The coding of this script is a strange brew of shell commands
                     40: with perl.

                     51: # "all the gunk we have been working on", whereas the 
                     52: # "make tardist" command means a "carefully inventoried selection of gunk".

                     72: is what encapsulates the stable releases of the LON-CAPA software (as
                     73: well as ensuring that LON-CAPA's distributability does not rely solely on
                     74: CVS software).
