       dkp - Diablo program to manage DKP databases

       dkp [-x]	[-r] [-w] [-d] [-s] [-t] filename [key [tok=data]] [ < input ]

       DKP  manages  KP	databases.  Currently Diablo has only one KP database,
       the active file,	called  issues a command to	the parent di-
       ablo  server.   The  command  allows  a	key and	optional tok=data (for
       writes) to be specified on the command line.  If	no key/data is	speci-
       fied, DKP takes key or key tok=data lines from the standard input.  The
       data may	not contain spaces, tabs, or newlines.

       -x - cause the specified	key (or	keys on	stdin, one  per	 line)	to  be
       deleted from the	database.

       -r - lookup the specified key and print the record.

       -w - write the specified	tok=data to the	database for the record	speci-
       fied by the given key.  A record	can have  multiple  tokens  associated
       with it but DKP currently accepts only one at a time.

       -d - Turn on debugging

       -s  -  Force the	KP database to be sorted in-place.  This option	is not
       normally	necessary, but is useful as a safety precaution	if you believe
       the database has	been manually edited.

       -t  - Trim the KP database, removing dead records.  This	will only work
       if no other processes have the specified	KP database open.   It	should
       be done on once a month.  If you are generating a fresh dac- from some other source, always run dkp -t on it	to  clear  out
       all the temporary junk.	filename - specify the name of the KP database
       file.  This is a	required parameter.

General	KP database maintenance
       KP databases can	be manually edited, but	only if	there  are  no	active
       references.  If you have	an editor capable of performing	an flock, such
       as nvi, your editor will	warn you if other processes have active	refer-
       ences to	the database because the database code maintains several locks
       on the database file.

       KP databases can	be replaced by generating a new	copy and  renaming  it
       over the	old, but if active references exist they will continue to work
       on the old, possibly until they close.  Since the  diablo  reader  code
       leaves active opens on the database, you should use only the
       dkp program to fix it unless you	shut down the reader entirely.

       KP databases handle changes in record size by marking the old record as
       deleted	(a  '-'	 instead  of  a	'+') and appending a new record.  This
       means that garbage can collect in the database file.  The  garbage  can
       be pruned safely	with 'dkp -t'.	DO NOT USE A GREP/RENAME TO PRUNE A KP

       Diablo gives instructions on how	to prune its various KP	 databases  by
       example,	usually	in the adm/ or samples/	directory.
