I want to keep my main .hgrc
in revision control, because I have a fair amount of customization it in, but I want to have different author names depending on which machine I'm using (work, home, &c.).
The way I'd do this in a bash script is to source a host-local bash script that is ignored by Mercurial, but I'm not sure how to do this in the config file format Mercurial uses.
