+dnl AM_PATH_LIBGCRYPT([MINIMUM-VERSION,
+dnl [ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND ]]])
+dnl Test for libgcrypt and define LIBGCRYPT_CFLAGS and LIBGCRYPT_LIBS.
+dnl MINIMUN-VERSION is a string with the version number optionalliy prefixed
+dnl with the API version to also check the API compatibility. Example:
+dnl a MINIMUN-VERSION of 1:1.2.5 won't pass the test unless the installed
+dnl version of libgcrypt is at least 1.2.5 *and* the API number is 1. Using
+dnl this features allows to prevent build against newer versions of libgcrypt
+dnl with a changed API.
+dnl
+dnl If a prefix option is not used, the config script is first
+dnl searched in $SYSROOT/bin and then along $PATH. If the used
+dnl config script does not match the host specification the script
+dnl is added to the gpg_config_script_warn variable.
