NAME
       htdump - write out an ASCII-text version of the document database

SYNOPSIS
       htdump [options]

DESCRIPTION
       Htdump writes out an ASCII-text version of the document database in the
       same form as the -t option of htdig.

OPTIONS
       -a     Use alternate work  files.  Tells	 htdump	 to  append  .work  to
	      database	files,	allowing  it  to  operate  on  a second set of
	      databases.

       -c configfile
	      Use the specified configfile instead of the default.

       -v     Verbose mode. This doesn't have much effect.

File Formats
       Document Database
	      Each line in the file starts with the document id followed by  a
	      list  of	fieldname : value separated by tabs. The fields always
	      appear in the order listed below:

       u      URL

       t      Title

       a      State (0 = normal, 1 = not found, 2 = not indexed, 3 = obsolete)

       m      Last modification time as reported by the server

       s      Size in bytes

       H      Excerpt

       h      Meta description

       l      Time of last retrieval

       L      Count of the links in the document (outgoing links)

       b      Count of the links to the document (incoming links or backlinks)

       c      HopCount of this document

       g      Signature of the document used for duplicate-detection

       e      E-mail address to use for a notification message from htnotify

       n      Date to send out a notification e-mail message

       S      Subject for a notification e-mail message

       d      The  text	 of  links  pointing  to  this	document.   (e.g.   <a
	      href="docURL">description</a>)

       A      Anchors in the document (i.e. <A NAME=...)

       Word Database
	      While  htdump  and  htload  don't	 deal  with  the word database
	      directly, it's worth mentioning it here because you need to deal
	      with  it	when  copying  the  ASCII databases from one system to
	      another. The initial word database produced by htdig is  already
	      in  ASCII	 format,  and  a  binary  version of it is produced by
	      htmerge, for use by htsearch. So, when you copy over  the	 ASCII
	      version of the document database produced by htdump, you need to
	      copy over the wordlist as well, then  run	 htload	 to  make  the
	      binary  document database on the target system, followed by run-
	      ning htmerge to make the word index.

       Each line in the word list file starts with the word
	      followed by a list of fieldname : value separated by  tabs.  The
	      fields  always  appear  in the order listed below, with the last
	      two being optional:

       i      Document ID

       l      Location of word in document (1 to 1000)

       w      Weight of word based on scoring factors

       c      Count of word's appearances in document, if more than 1

       a      Anchor number if word occurred after a named anchor

FILES
       /etc/htdig/htdig.conf
	      The default configuration file.

       /var/lib/htdig/db.docs
	      The default ASCII document database file.

       /var/lib/htdig/db.wordlist
	      The default ASCII word database file.
