Specifying RequireJS config file on command line

How can I specify the RequireJS config file on the command line? I've seen this requireConfig option in the API, but it's not mentioned as a command line option. I attempted the following

dependo -f amd --requireConfig subdir/Config.js . >dependencies.html

in the directory under which all source exists, but that had no effect in limiting the dependencies to those rooted in the Config.js file.

Start with the dependo command-line entry point and compare its options with the API's requireConfig option. Reproduce the reported command using subdir/Config.js, then verify that the command limits the dependency graph to modules rooted in that configuration file.
