NAME
       bogotune - find optimum parameter settings for bogofilter

SYNOPSIS
       bogotune [-v] [-c config] [-C] [-d dir] [-D] [-r value] [-T value]
		-n okfile [[-n] okfile [...]] -s spamfile [[-s] spamfile [...]] [-M file]

       bogotune [-h]

DESCRIPTION
       Bogotune tries to find optimum parameter settings for bogofilter. It needs at least one
       set each of spam and non-spam messages. The production wordlist is normally used, but it
       can be directed to read a different wordlist, or to build its own from half the supplied
       messages.

       In order to produce useful results, bogotune has minimum message count requirements. The
       wordlist it uses must have at least 2,000 spam and 2,000 non-spam in it and the message
       files must contain at least 500 spam and 500 non-spam messages. Also, the ratio of spam to
       non-spam should be in the range 0.2 to 5. If you direct bogotune to build its own
       wordlist, it will use the half the input or 2000 messages (whichever is larger) for the
       wordlist.

       Message files may be in mbox, maildir, or MH folder or any combination. Msg-count files
       can also be used, but not mixed with other formats.

OPTIONS
       The -h option prints the help message and exits.

       The -v option increases the verbosity level. Level 1 displays the scan output in detail
       instead of using a progress meter.

       The -c filename option tells bogofilter to read the config file named.

       The -C option prevents bogotune from reading a configuration file.

       The -d dir option specifies the directory for the database. See the ENVIRONMENT section
       for other directory setting options.

       The -D option tells bogotune to build a wordlist in memory using the input messages. The
       messages are read and divided into two groups. The first group is used to build a wordlist
       (in ram) and the second is used for tuning. To meet the minimum requirements of 2000
       messages in the wordlist and 500 messages for testing, when -D is used, there must be 2500
       non-spam and 2500 spam in the input files. If there are enough messages (more than 4000),
       they will be split evenly between wordlist and testing. Otherwise, they will be split
       proportionately.

       The -n option tells bogotune that the following argument is a file (or folder) containing
       non-spam. Since version 1.0.3, multiple arguments to the -n option can be given. All
       non-option arguments until the next -s option will be treated as though they had been
       preceded by -n

       The -s option tells bogotune that the following argument is a file (or folder) containing
       spam. It can be repeated as often as necessary. Since version 1.0.3, multiple arguments to
       the -s can be given. All non-option arguments until the next -n option will be treated as
       though they had been preceded by -s.

       The -r value option tells bogotune to use the following parameter as the robx value.

       The -T value option tells bogotune to use the following parameter as fp target value.

       The -M file option tells bogotune to convert the file to message count format. This format
       provides a sorted list of each message's unique tokens, along with their ham and spam
       counts. Sorting hides the sense of the messages quite effectively, thus protecting
       privacy. The message-count format allows bogotune and bogofilter to score messages quickly
       without needing the original token database.

ENVIRONMENT
       Bogofilter uses a database directory, which can be set in the config file. If not set
       there, bogofilter will use the value of BOGOFILTER_DIR. Both can be overridden by the
       -ddir option. If none of that is available, bogofilter will use directory
       $HOME/.bogofilter.

BUGS
       Bogotune is not particularly robust when presented with garbage input.
