1/*
2** sofa.h - SOFA-over-ERFA compatibility shim for INDI SPK Math Plugin
3**
4** Maps the SOFA iauXxx API onto the ERFA eraXxx API so that the SPK C
5** sources (spk_vtel.c, spk_pmfit.c, spk_astr.c) can be compiled unchanged
6** against the system liberfa library.
7**
8** ERFA (Essential Routines for Fundamental Astronomy) is a BSD-licensed
9** fork of SOFA with identical mathematics. See https://github.com/liberfa/erfa
10**
11** Usage: add the directory containing this header to the compiler include
12** path, then link against -lerfa. This is a header-only shim.
