The default tool -adopted by the community to manage projects is -[[http://leiningen.org][leiningen]]. For those of you who don't know -what =lein= is, it's a tool to automate your Clojure project: it will -boostrap a new project, install the dependencies, and there's a plugin -mechanism to extend the default possibilities of the tool. - -One of the nice feature of the tool is the *checkouts* directory. From -the -[[https://github.com/technomancy/leiningen/blob/preview/doc/FAQ.md][FAQ]]: - -#+BEGIN_QUOTE - If you create a directory named checkouts in your project root and - symlink some other project roots into it, Leiningen will allow you to - hack on them in parallel. -#+END_QUOTE - -For Python projects at [[http://www.saymedia.com/careers][$work]] I use -[[http://virtualenvwrapper.readthedocs.org/en/latest/][virtualenvwrapper]] -to easily work on them without having to deal with conflicting -dependencies. When I need to change a library that is used by one of the -project, usually I go to the virtualenv directory and create a symlink -so it uses the one I'm editing. - -What I really want is a mechanism similar to =lein=, where I can have a -*checkouts/* directory inside the main project, where I can clone a -library or create a symlink.
