+timer_lib  -  v1.0  -  Public Domain  -  2011 Mattias Jansson
+
+This library provides a cross-platform interface to measure
+elapsed time with (at least) millisecond accuracy. The latest
+source code is always available at
+
+https://github.com/mjansson/timer_lib
+
+This library is put in the public domain; you can redistribute
+it and/or modify it without any restrictions.
+
+For a complete cross-platform application framework, look at
+the foundation library available at
+
+https://github.com/mjansson/foundation_lib
+
+
+VERSION HISTORY
+
+ 0.1  (2011-03-15)  Initial release
+ 0.2  (2011-03-20)  Removed timer type (always high precision)
+                    Fixed timer_ticks_per_second declaration
+                    Added test application
+ 0.3  (2011-03-22)  Removed unused error checks in POSIX code
+                    Made timeGetTime fallback optional in Windows code (define USE_FALLBACK to 1)
+                    Fixed check of QPC weirdness (signed issue)
+ 0.4  (2011-03-23)  timer_lib_initialize() returns non-zero if failed (no high precision timer available)
+                    Changed POSIX path to use CLOCK_MONOTONIC
+                    POSIX timer_system use CLOCK_REALTIME for actual timestamp
+                    Addded Mach-O path for MacOS X
+                    Changed POSIX path to use nanosecond frequency as returned by clock_gettime
+ 0.5  (2012-10-01)  Merged (cleaned up) MacOSX build fixes from Nicolas Léveillé
+ 0.6  (2013-01-11)  Simplified API, only using tick_t type as timestamp and removing custom timer struct
+                    Removed old legacy fallback code for Windows platform
+ 0.7  (2013-01-11)  Using platform_lib for platform and compiler abstraction
+ 0.8  (2013-07-30)  Made library standalone with no deps (not using deprecated platform_lib)
+ 1.0  (2021-12-15)  Updated and cleaned up for clang 10+ and Visual Studio 2022
