      needed by a classical installation with the command:
        >> pip install -r creme/requirements.txt
    - If you want a customised installation, you'll have to install the package yourself,
      depending on which apps or SQL server you want. For PostGreSQL, install the package 'psycopg2':
        >> pip install psycopg2

You have to know how to install a Django application.

Upgrade notice : if you already have a Creme installation, upgrade the version one by one
(eg: do not try to upgrade from 1.1 to 1.3, upgrade to 1.2 and then 1.3).

See the creme/ and set your parameters (or put them in a new file called 'creme/' instead).
When you have chosen the creme apps you want (by commenting the unwanted ones), and configured the DB parameters
run the following commands in the root directory:

If you are upgrading from Creme 1.5:
    >> python migrate --fake-initial
else (ie: new installation):
    >> python migrate

>> python generatemedia
[Do not worry about 'URL not found' messages]
>> python creme_populate

And if you are upgrading from Creme 1.5:
 - Clean all existing sessions, for example like this:
    >> python shell
    > from django.contrib.sessions.models import Session
    > Session.objects.all().delete()

You should load the time zone tables. On Unix servers, it can be done with :
    >> mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql

- If you got some problems with PIL, check if you are using the legacy PIL (that was in our old requirements) or
  its fork Pillow (new requirement). The best thing to do is first to uninstall PIL, and then install Pillow.
