query on LDIF to BDB format

["Meenakshi Vohra" <meenakshi_vohra@symantec.com>]

Hello,

If someone could help with this query of mine it would really help.

I keep reading this line all over the internet "The LDAP software
package you're going to get comes with an utility to convert LDIF files
to the BDB format". 

I would like to know if the BDB format being mentioned here is the
actual BDB data (text file) format that BDB dump db_dump and BDB load
db_load utilities expect or is this something specific to LDAP or does
it automatically creates the BDB database reading this LDIF format file.
If so how does it create the secondary indexes in BDB.

Also how big is this utility and what is it called ?

Regards,

Meenakshi
