Kerberos IV code, based on a merge of fixed code from KTH and original

4.4BSD Lite code (international edition).  Provides all functionality
from the original 4.4BSD code plus standard Kerberos elements that were
omitted in the 4.4BSD code.

+.TH KDB_INIT 8 "Kerberos Version 4.0" "MIT Project Athena"
+.SH NAME
+kdb_init \- Initialize Kerberos key distribution center database
+.SH SYNOPSIS
+kdb_init [ 
+.B realm
+]
+.SH DESCRIPTION
+.I kdb_init
+initializes a Kerberos key distribution center database, creating the
+necessary principals.
+.PP
+If the optional
+.I realm
+argument is not present,
+.I kdb_init
+prompts for a realm name (defaulting to the definition in /usr/include/krb.h).
+After determining the realm to be created, it prompts for
+a master key password.  The master key password is used to encrypt
+every encryption key stored in the database.
+.SH DIAGNOSTICS
+.TP 20n
+"/kerberos/principal: File exists"
+An attempt was made to create a database on a machine which already had
+an existing database.
+.SH FILES
+.TP 20n
+/kerberos/principal.pag, /kerberos/principal.dir
+DBM files containing database
+.TP
+/usr/include/krb.h
+Include file defining default realm
+.SH SEE ALSO
