[Zope] export product outside zope

[John Hunter]

I have just finished a python script that solve the problem of
exporting a remote zope folder to the local filesystem.  The script
takes a number of command line arguments to specify the remote
server/folder/port and the local output dir.  You can call this script
from cron if you trust hiding your password in the /etc/cron.daily
root folder.  Otherwise, you can supply it to a getpass call

Hope someone else finds it useful...

#  -d              optional -- debug mode.  If supplied, then just print the wget command

#  -f FOLDER       required -- remote folder to backup
#  -o LOCALDIR     optional --  local output directory, default '.'
#  -p PORT         optional --  default 8080

Here is an example file from /etc/cron.daily which calls this script.
If you hardcode your user:pass, make sure you make the file 'chmod
600'

--- begin /etc/cron.daily/zope_course_export ---
#!/bin/sh
# Export the course folder to /backup/
/usr/local/bin/python2.1 /usr/local/bin/zope_export.py -u myuser:mypass -o /backup -f SRP2002 -s myhost.com
--- end /etc/cron.daily/zope_course_export ---
