The SOFA original has a role as a reference standard +for the IAU and IERS, and consequently redistribution is permitted only +in its unaltered state. The ERFA version is not subject to this +restriction and 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 that +you are using a library derived from SOFA, rather than SOFA itself. + + +TERMS AND CONDITIONS + +Redistribution and use in source and binary forms, with or without +modification, are permitted provided that the following conditions are met: + +1 Redistributions of source code must retain the above copyright + notice, this list of conditions and the following disclaimer. + +2 Redistributions in binary form must reproduce the above copyright + notice, this list of conditions and the following disclaimer in the + documentation and/or other materials provided with the distribution. + +3 Neither the name of the Standards Of Fundamental Astronomy Board, the + International Astronomical Union nor the names of its contributors + may be used to endorse or promote products derived from this software + without specific prior written permission. + +THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS +IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED +TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A +PARTICULAR PURPOSE ARE DISCLAIMED.
