+# SYNOPSIS
+#
+#   AX_CHECK_OPENSSL([action-if-found[, action-if-not-found]])
+#
+# DESCRIPTION
+#
+#   Look for OpenSSL in a number of default spots, or in a user-selected
+#   spot (via --with-openssl).  Sets
+#
+#     OPENSSL_INCLUDES to the include directives required
+#     OPENSSL_LIBS to the -l directives required
+#     OPENSSL_LDFLAGS to the -L or -R flags required
+#
+#   and calls ACTION-IF-FOUND or ACTION-IF-NOT-FOUND appropriately
+#
+#   This macro sets OPENSSL_INCLUDES such that source files should use the
+#   openssl/ directory in include directives:
+#
+#     #include <openssl/hmac.h>
