     * 
     * If enabled, SmbFile instances starting with their first use will hold a reference to their tree.
     * This means that trees/sessions/connections won't be idle-disconnected even if there are no other active
     * references (currently executing code, file descriptors).

encourage the widest possible use of a certain library, so that it becomes
a de-facto standard.  To achieve this, non-free programs must be
allowed to use the library.  A more frequent case is that a free
library does the same job as widely used non-free libraries.  In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
