GNU Stow is a symlink farm manager which takes distinct packages of software and/or data located in separate directories on the filesystem, and makes them appear to be installed in the same place. For example, /usr/local/bin could contain symlinks to files within /usr/local/stow/emacs/bin
... [More], /usr/local/stow/perl/bin etc., and likewise recursively for any other subdirectories such as .../share, .../man, and so on.
This is particularly useful for keeping track of system-wide and per-user installations of software built from source, but can also facilitate a more controlled approach to management of configuration files in the user's home directory, especially when coupled with version control systems. [Less]
nautilus-follow-symlink is a nautilus extension that adds a menu entry on symbolic links to directories which open the pointed directory (the real path).
It does so both when right clicking on a the folder icon or on the contents of an opened symbolic link.
