+
+## fetch-mirror-sites ##
+
+Fetch a list of mirrors, extract the URLs of FTP and HTTP(S) mirrors,
+and print them to standard output in a format suitable for
+[`mirror_sites.tcl`][mirror_sites].
+
+ fetch-mirror-sites [-a] [-K <curl config>] [--] <source>
+
+* `-a`: Output all URLs. By default, we "deduplicate" by outputting
+ only one URL per [fully qualified domain name][fqdn], prioritizing
+ HTTPS over HTTP over FTP. (This is a naïve attempt to avoid trying
+ a single host multiple times, once per available protocol. URLs
+ referring to the same host by different FQDNs must be culled
+ manually.)
+
+* `-K`: Specify the path to a `curl(1)` config file to use when
+ fetching the source (or `-` to read a config from standard input).
+ The argument is passed directly to `curl --config`, so refer to the
+ [`curl(1)` documentation][curl] for details.
+
+* `<source>`: The name of a supported mirror list.

+
+## port-checkmirrors ##
+
+Verify the integrity of ports' distfiles on all applicable mirrors.
+
+ port-checkmirrors <port spec>
+
+* `port spec`: Any valid MacPorts port specification, including
+ expressions and pseudo-portname selectors.
