+/// @brief Full callout library
+///
+/// This is source of a test library for various test (LibraryManager and
+/// HooksManager).  The characteristics of the library produced from this
+/// file are:
+///
+/// The characteristics of this library are:
+///
+/// - All four framework functions are supplied (version(), load(),
+///   unload() and multi_threading_compatible()), with unload()
+///   creating a marker file.  The test code checks for the presence
+///   of this file, so verifying that unload() has been run.
+///
+/// - One standard and two non-standard callouts are supplied, with the latter
+///   being registered by the load() function.
+///
+///   All callouts do trivial calculations, the result of all being called in
+///   sequence being
+///
+///   @f[ ((7 * data_1) - data_2) * data_3 @f]
+///
+///   ...where data_1, data_2 and data_3 are the values passed in arguments of
+///   the same name to the three callouts (data_1 passed to hookpt_one, data_2
+///   to hookpt_two etc.) and the result is returned in the argument "result".
