+NGA doesn't provide versioned sources of the library, meaning that with each new release existing sources for old
+releases will be lost and builds will no longer be reproducible (original issue and rationale: https://github.com/conan-io/conan-center-index/pull/6512).
+
+This folder contains snapshots of the sources as they are retrieved from `https://earth-info.nga.mil/php/download.php?file=wgs-mastertgz`:
+
+ * `geotrans-3.8.tgz`: retrieved on 2021-10-13
