You're absolutely right. I mean, what's the point of even having files with code in them? I want to just draw my matrix block pattern in MS Paint and have this automatically be run in parallel. -or- Why can't I just clone petsc-dev/src/ts??? I don't want the whole goddamn source tree!

Generally you want fewer people with root access the closer you get to the root directory since the more harm they can do. So for example petsc/releases would only have Satish and one other with admin.

> > No I mean I want > > petsc/releases/petsc-3.1 > petsc/tools/parsing/BarrysNewHTMLMunger > Sounds like you want a "traditional filesystem hierarchy" and like I said before, your request will fall on deaf ears. This is the same request that mercurial-dev gets from people switching from subversion: "I only want to check out a subdirectory, not the whole project!" to which the common response is, "You should rethink your 'project' if you only want a subdirectory." Take a look at subrepos and subpaths: http://mercurial.selenic.com/wiki/Subrepository http://mercurial.selenic.com/wiki/SubrepoRemappingPlan and maybe projrc: http://mercurial.selenic.com/wiki/ProjrcExtension?action=show&redirect=Subp… For what it's worth, I never liked petsc-dev being in a different folder than petsc-3.x. It is not confusing to have them all like so: petsc/petsc-3.1 petsc/petsc-dev
