generally i reserve this type of stuff into the __init__ method of the
object... hence i don't clutter up my manage_add method with code thats
not directly relevant to its function.

anyways, such is mainly a style matter.. 

to answer your question...
here is a method i call from my __init__  method of a python product.


def setup_catalog(self):
    ''' setups catalog for searching news channels '''
                
    id = 'news_catalog'
    catalog = Products.ZCatalog.ZCatalog.ZCatalog(id)
    self._setObject(id, catalog)
                
    # setup indexes and such
    self.news_catalog.manage_addColumn('description')

    self.news_catalog.manage_addColumn('Date')
    self.news_catalog.manage_addIndex('Date', 'FieldIndex')
                
    self.news_catalog.manage_addColumn('ChannelName')
    self.news_catalog.manage_addIndex('ChannelName', 'FieldIndex')
                
    self.news_catalog.manage_addColumn('link')
    self.news_catalog.manage_addIndex('link', 'FieldIndex')

    self.news_catalog.manage_addIndex('SearchableText', 'TextIndex')

    # get rid of defaults
    self.news_catalog.manage_delColumns(['bobobase_modification_time',
'summary'])
   
self.news_catalog.manage_delIndexes(['bobobase_modification_time', 	             
                                      'PrincipiaSearchSource'])
                
    return 1


you can also do it from a dtml-method.

i'd don't have the exact syntax handy...

but i'll take a stab at it

the Folder, Image, Document, Method manage_adds are globally available
methods... to add a product you need

see the howto on adding zclasses programamtically for examples/more
info.

if i remember correctly the syntax is something like

<dtml-with "Control_Panel.Products['ZCatalog']">
	<dtml-call "manage_addZCatalog('foo', 'bar', _.None)">
</dtml-with>

but i would check that...
