+======Synopsis:======
+$convert(<ip address|hostname>)
+======Technical:======
+This function does a DNS lookup on the given address.  For an IP address,
+it attempts to find the corresponding Internet hostname.  For a hostname,
+it attempts to find the corresponding IP address.
+======Practical:======
+This function does effectively the same thing as $[[iptoname]]() and
+$[[nametoip]]().  It is mostly useful when you want to convert an address, but
+you aren't sure if the input will be an IP address or not.
+======Returns:======
+IP address or hostname corresponding to input, or nothing on error
+======Examples:======
+<file>
+$convert(some.school.edu)       returns IP address for "some.school.edu"
+$convert(192.168.1.1)           returns hostname for "192.168.1.1"
+</file>
+An easy example of this in a script is:
+<file>
+alias dns {
+  echo Matched $0 to $convert($0)
+}
+</file>
