"""Simple HTTP Server With Upload.

This module builds on BaseHTTPServer by implementing the standard GET

From the man page for ssh:

     -f      Requests ssh to go to background just before command execution.  This is useful if ssh is going to ask 
             for passwords or passphrases, but the user wants it in the background.  This implies -n.  The recommended way 
             to start X11 programs at a remote site is with something like ssh -f host xterm.

             If the ExitOnForwardFailure configuration option is set to “yes”, then a client started with -f will wait 
             for all remote port forwards to be successfully established before placing itself in the background.

"""Add permissions for proxy model.

This is needed because of the bug https://code.djangoproject.com/ticket/11154
in Django (as of 1.6, it's not fixed).

When a permission is created for a proxy model, it actually creates if for it's
base model app_label (eg: for "article" instead of "about", for the About proxy
model).

The easiest way to load the Mysql Time Zone tables from your Mac OS time zone fields is via this command:

mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql

However, on many systems like mine that will fail because some of the time zone information is incompatible with the database schema for the time zone tables.

Therefore, you'll want to load the time zone information into a text file and edit it to only include the time zones you need. (Or, attempt to find the data breaking the import.)

mysql_tzinfo_to_sql /usr/share/zoneinfo > zone_import.sql
