+.SH "NAME"
+variants.conf \- Global variant configuration file of the MacPorts system
+.SH "DESCRIPTION"
+.sp
+\fBvariants\&.conf\fR is the configuration file used to globally select or deselect certain variants on all ports installed by MacPorts\&. Changes in this file will affect all ports that are installed after the file was changed\&.
+.sp
+For a description of what variants are and how they work, see \fBport-variants\fR(1)\&.
+.sp
+\fBvariants\&.conf\fR is read by the \fBport\fR command\&. In the file, lines beginning with \fI#\fR are comments, empty lines are ignored\&. Each line in the file is a space\- or tab\-delimited list of zero or more variants, where each variant is either explicitly enabled or disabled using a leading \fI+\fR or \fI\-\fR\&. In EBNF:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+line = variant, { space, variant }
+space = \*(Aq \*(Aq | \*(Aq\et\*(Aq
+variant = ( \*(Aq+\*(Aq | \*(Aq\-\*(Aq ), name
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+where \fIname\fR is the name of the variant\&. Variants that are not provided by a port (or no port at all) are silently ignored\&.
+.SH "FILES"
+.sp
+The path of the \fIvariants\&.conf\fR file is specified in the \fBvariants_conf\fR option of \fBmacports.conf\fR(5)\&. It defaults to \fI${prefix}/etc/macports/variants\&.conf\fR\&. There is no user\-specific \fIvariants\&.conf\fR file, but support for this can be emulated by setting \fIvariants\&.conf\fR in the user\-specific \fBmacports.conf\fR(5) file\&.
+.SH "EXAMPLES"
+.sp
+To prefer the \fI+quartz\fR variant over \fI+x11\fR, you can add the following line to your variants\&.conf:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+\-x11 +quartz
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+This will disable all x11 variants and enable the quartz variant, when it exists\&.
+.sp
+Similarly, if you want all your ports to support multiple architectures, you can enable the universal variant by default:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
++universal
+.fi
+.if n \{\
+.RE
+.\}
