Summary:  Installs the default values of a WP blog during the creation of a new blog

Details:  This function does a lot, and depending on how you want your blogs setup, may be useful to modify.  It sets up default values for such things as the blogroll, the first post, the first comment, the default category.  Of these options, only the default post can be set in Blog Options, so for finer tuning of the end-user experience, editing this file might be helpful.
