 /* The GnuPG project consists of many components.  Error codes are
  * exchanged between all components.  The common error codes and their
  * user-presentable descriptions are kept into a shared library to
  * allow adding new error codes and components without recompiling any
  * of the other components.  In addition to error codes this library
  * also features several other groups of functions which are common to
  * all GnuPG components.  They may be used by independet project as
  * well.  The interfaces will not change in a backward incompatible way.
  *
  * An error code together with an error source build up an error
  * value.  As the error value is been passed from one component to
  * another, it preserves the information about the source and nature
  * of the error.
  *
  * A component of the GnuPG project can define the following macros to
  * tune the behaviour of the library:
  *
  * GPG_ERR_SOURCE_DEFAULT: Define to an error source of type
  * gpg_err_source_t to make that source the default for gpg_error().
  * Otherwise GPG_ERR_SOURCE_UNKNOWN is used as default.
  *
  * GPG_ERR_ENABLE_GETTEXT_MACROS: Define to provide macros to map the
  * internal gettext API to standard names.  This has only an effect on
  * Windows platforms.
  *
  * GPGRT_ENABLE_ES_MACROS: Define to provide "es_" macros for the
  * estream functions.
  *
  * GPGRT_ENABLE_LOG_MACROS: Define to provide short versions of the
  * log functions.
  *
  * GPGRT_ENABLE_ARGPARSE_MACROS: Needs to be defined to provide the
  * mandatory macros of the argparse interface.
