maybe a silly question, I'm not very used to VCS
is it possible to set just one (or some) subfolder/s of a project (and possibly the very same folder/s of other projects) under a common repository?
I tried in many ways (with a local mercurial on my PC) in some fake projects, but without results
what I want is to manage some "library folders" (not the whole project) with common files used in many projects, to detect and distribute updates
thank you in advance for any clue ;)
