+/**
+ * When installed, this plugin will create a relative symlink from $HOME/website to /web when:
+ * - domain is created or updated
+ * - shell user is created or updated
+ *
+ * Its purpose is to make it easier for users to navigate to their web folder. If a file named website/ already exists
+ * it is not overwritten.
+ *
+ * Example:
+ *
+ * $ ls -al /var/www/domain.com/home/username
+ * total 12
+ * drwxr-x--- 3 web1    client1    4096 Nov  4 22:19 .
+ * drwxr-xr-x 4 root    root       4096 Nov  4 22:19 ..
+ * lrwxrwxrwx 1 root    root          9 Nov  4 22:19 website -> ../../web
