+SOFA ANSI C Library Formatted for Bazel Integration. All source code is
+identical to the original release (dated 2019-07-22) except for the relocation
+of header files to the `include/` directory. The library can be built with:
+
+    bazel build //:sofa

+SOFA-Issue: 2019-07-22
+
+This is the IAU Standards of Fundamental Astronomy (SOFA) Libraries product, 
+issued on 2019-07-22.  The tag `SOFA-Issue' above defines this release and 
+differentiates it from previous or subsequent releases of the SOFA product.
+The 00READ.ME file must remain with this distribution set.
+
+Changes made since the previous release are noted in the file changes.lis. 
+
+Notes:
+
+1/  Unix users:  The distribution set contains a simple makefile which 
+    can be used to create a single object library for the SOFA Libraries.
+    To build the object library:
+
+    a/  Examine the makefile to be sure definition of the C compiler
+        is correct for your system.  You need an ANSI standard compliant
+        C compiler.  Edit the CCOMPC macro in the makefile as necessary.
+
+    b/  To create libsofa.a, execute make:
+
+        % make
+
+        (where % is the shell prompt).
+
+    c/  To remove the object files:
+
+        % make clean
+
+    To link with the SOFA library, include the library in the compile/link
+    command in the normal Unix fashion, eg:
+
+        % gcc myprog.c -o myprog libsofa.a
+
+    You should specify the appropriate C compiler name for `gcc'
+    in the above command sequence.
+
+
+2/  Windows/DOS/Mac users:  There is no `build' procedure to create a linkable
+    object library or DLL for the SOFA Libraries.  This is due to the many
+    different C compilers and development environments available on
+    Windows/DOS and Mac machines.  
+
+    To use the SOFA routines with your program(s), you must use your preferred
+    development environment to create the appropriate library or DLL.

+            Updates for SOFA Release 15 : 2019 July 22
+            - - - - - - - - - - - - - - - - - - - - - - -
+
+Summary of Changes
+------------------
+The changes fall into the following categories:
+
+1. Wrong sign in the ANSI C function iauTdbtcb corrected.
+
+2. Update DAT release year.
+
+3. Implementation of four new routines that have been added to the
+   Star Catalog Conversions section dealing with the transformation
+   between the FK4 and the FK5 reference systems.  These routines
+   have have been included partly for completeness but mainly so that
+   positions in publications pre-1984 can be properly handled.  They
+   cover conversions between B1950.0 FK4 and J2000.0 FK5, with and
+   without proper motion.
+
+4. Enhancement of 17 routines that compare the two components of
+   given date/time arguments to minimize rounding errors, so that
+   optimum results are achieved even when one of the arguments is
+   negative.  (SOFA is grateful to the Astropy group for drawing
+   attention to the deficiency.)
+
+5. Due to introducing these new routines, the Astrometry Tools
+   Cookbook, the test program and other supporting files have also
+   been updated.
+
+6. Miscellaneous typographical corrections and improvements to
+   various other documents.
+
