+**  Fundamental argument, IERS Conventions (2003):
+**  mean elongation of the Moon from the Sun.
+**
+**  Given:
+**     t     double    TDB, Julian centuries since J2000.0 (Note 1)
+**
+**  Returned (function value):
+**           double    D, radians (Note 2)
+**
+**  Notes:
+**
+**  1) Though t is strictly TDB, it is usually more convenient to use
+**     TT, which makes no significant difference.
+**
+**  2) The expression used is as adopted in IERS Conventions (2003) and
+**     is from Simon et al. (1994).

+**  
+**  The ERFA version is intended to retain identical functionality to

+**  file names, as set out in the SOFA license conditions.  The SOFA
+**  original has a role as a reference standard for the IAU and IERS,

+**  therefore can be included in distributions which do not support the
+**  concept of "read only" software.
+**  
+**  Although the intent is to replicate the SOFA API (other than
+**  replacement of prefix names) and results (with the exception of
+**  bugs;  any that are discovered will be fixed), SOFA is not
+**  responsible for any errors found in this version of the library.
+**  
+**  If you wish to acknowledge the SOFA heritage, please acknowledge
