 Vim Plugins werden prinzipiell von github.com bezogen. Für spezielle Anwendungsfälle (github.com ist per firewall gesperrt), kann man diese auch in eigenen Repos hosten. Um diese eigenen Repos zu verwenden, muss in ~/.bashrc die Variable entsprechend gesetzt werden. Es ist ein Verzeichnis anzugeben, unter dem alle Pluginrepos als bare-Repos gecloned werden. Wichtig ist, dass die Usernamenverzeichnisse von github.com hier auch vorhanden sind, damit ohne dieser gesetzten Variable die Plugins direkt von github.com geladen werden können.
