As far as I can tell std.process can only run commands in the working

certain program inside a subdirectory on windows and can't get it to work:

myproject

So my executable has "myproject" as working directory. And I want to 
execute "dmd" with "subdir" as working directory.

Thanks. That works. It still would be nice if std.process had this in 
its API.

this is a command use case. Further,relying on shell such as  cd subdir &&
foo is fragile: if it fails, we're not sure whether it's because it
couldn't cd to subdir or because of foo.

Woudl the following be as efficient?
system_in_dir(string dir, string action){
auto path=getcwd
scope(exit)
  chdir(path)
chdir(dir)
system(action)
}

Well at least the windows API call CreateProcess already has a parameter 
which you can use to specify the working directory. Its just not exposed 
in the implementation of std.process. I don't know how things are on 
linux though.
