 .SH DESCRIPTION
-\fBvmm\fR(1) reads configuration data from \fIvmm.cfg\fP.
+.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
-The configuration file is split in multiple sections. A section starts with the
-section  name, enclosed in square brackets '[' and ']' (e.g. \fB[database]\fP),
-followed by \'option=value' pairs (e.g. \fBhost = 127.0.0.1\fP).
-.br
-Whitespace around the '=' and at the end of a value is ignored.
-.PP
-Empty lines and lines starting with '#' or ';' will be ignored.
+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:
-.IP \(bu
+.TP 8
 .I Boolean
-to indicate if something is enabled/activated (true) or disabled/deactivated
-(false).
+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 \fBtrue\fP are: \fB1\fP, \fByes\fP, \fBtrue\fP and \fBon\fP.
+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
-Accepted values for \fBfalse\fP are: \fB0\fP, \fBno\fP, \fBfalse\fP and
-\fBoff\fP.
-.IP \(bu
-.I Int
-an integer number, written without a fractional or decimal component. For
-example \fB1\fP, \fB50\fP or \fB321\fP are integers.
-.IP \(bu
-.I String
-a sequence of characters and numbers. For example '\fBword\fP', '\fBhello
-world\fP' or '\fB/usr/bin/strings\fP'
-.SS SEARCH ORDER
-By default vmm looks for \fIvmm.cfg\fP in the following directories in the
-order listed:
+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:
