help: scripting help topic...

help: scripting help topic There are a lot of non-human consumers of Mercurial. And the challenges and considerations for machines consuming Mercurial is significantly different from what humans face. I think there are enough special considerations around how machines consume Mercurial that a dedicated help topic is warranted. I concede the audience for this topic is probably small compared to the general audience. However, lots of normal Mercurial users do things like create one-off shell scripts for common workflows that I think this is useful enough to be in the install (as opposed to, say, a wiki page - which most users will likely never find). This text is by no means perfect. But you have to start somewhere. I think I did cover the important parts, though.
