Comment:

 The configuration option for this in macports.conf is called
 `master_site_local`. You probably also want to set `patch_site_local` to
 the same value. Example:

 {{{
 master_site_local   http://distfiles.local/:mirror
 patch_site_local    http://distfiles.local/:mirror
 }}}

 These do not appear to be documented in the guide, so let's make this
 ticket be about the documentation request.

 There is also `archive_site_local` which is supposed to usable to specify
 a local site for binaries. Example:

 {{{
 archive_site_local  http://packages.local/:tbz2
 }}}

 However we also have archive_sites.conf and I'm not sure of the
 relationship between those two—which one takes precedence for example.
