.SH NAME

vmm.cfg \- configuration file for vmm

.\" -----------------------------------------------------------------------

.SH SYNOPSIS

vmm.cfg

.\" -----------------------------------------------------------------------

.SH DESCRIPTION

.BR vmm (1)

reads its configuration data from

.IR vmm.cfg .

.PP

The configuration file is split into multiple sections.

A section starts with the section name, enclosed in square brackets

.RB ` [ "' and `" ] ',

followed by

.RI ` option " = " value '

pairs.

.br

Whitespace around the `=' and at the end of a value is ignored.

Empty lines and lines starting with `#' or `;' will be ignored.

.PP

Each value uses one of the following data types:

.TP 8

.I Boolean

to indicate if something is enabled/activated (true) or

disabled/deactivated (false).

.br

Accepted values for

.I true

are:

.BR 1 , " yes" , " true" " and " on .

.br

Accepted values for

.I false

are:

.BR 0 , " no" , " false" " and " off .

.TP

.I Int

an integer number, written without a fractional or decimal component.

.br

For example

.BR 1 , " 50" " or " 321

are integers.

.TP

.I String

a sequence of characters and/or numbers.

.br

For example

.RB ` word "', `" "hello world" "' or `" /usr/bin/strings '

are strings.

.PP

Most options have a default value, shown in parentheses after the option's

name.

In order to use a option's default setting, comment out the line, either

with a

.BR # " or " ;

or simply remove the setting from

.IR vmm.cfg .

.PP

A minimal

.I vmm.cfg

would be:

.PP

.nf

[database]

user = me

pass = xxxxxxxx

[misc]

dovecot_version = 1.2.16

.fi
