+# 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>

+dnl @synopsis AX_DMD
+dnl
+dnl Test for the presence of a DMD-compatible D2 compiler, and (optionally)
+dnl specified modules on the import path.
+dnl
+dnl If "DMD" is defined in the environment, that will be the only
+dnl dmd command tested. Otherwise, a hard-coded list will be used.
+dnl
+dnl After AX_DMD runs, the shell variables "success" and "ax_dmd" are set to
+dnl "yes" or "no", and "DMD" is set to the appropriate command. Furthermore,
+dnl "dmd_optlink" will be set to "yes" or "no" depending on whether OPTLINK is
+dnl used as the linker (DMD/Windows), and "dmd_of_dirsep" will be set to the
+dnl directory separator to use when passing -of to DMD (OPTLINK requires a
+dnl backslash).
+dnl
+dnl AX_CHECK_D_MODULE must be run after AX_DMD. It tests for the presence of a
+dnl module in the import path of the chosen compiler, and sets the shell
+dnl variable "success" to "yes" or "no".
