+    \class QtLockedFile
+
+    \brief The QtLockedFile class extends QFile with advisory locking functions.
+
+    A file may be locked in read or write mode. Multiple instances of
+    \e QtLockedFile, created in multiple processes running on the same
+    machine, may have a file locked in read mode. Exactly one instance
+    may have it locked in write mode. A read and a write lock cannot
+    exist simultaneously on the same file.
+
+    The file locks are advisory. This means that nothing prevents
+    another process from manipulating a locked file using QFile or
+    file system functions offered by the OS. Serialization is only
+    guaranteed if all processes that access the file use
+    QtLockedFile. Also, while holding a lock on a file, a process
+    must not open the same file again (through any API), or locks
+    can be unexpectedly lost.
+
+    The lock provided by an instance of \e QtLockedFile is released
+    whenever the program terminates. This is true even when the
+    program crashes and no destructors are called.
+*/
