+It is much easier if you use GNU Automake instead writing your own
+Makefiles.  If you do that you don't have to worry about finding and
+invoking the @command{gpgme-config} script at all.  @acronym{GPGME}
+provides an extension to Automake that does all the work for you.
+
+@c A simple macro for optional variables.
+@macro ovar{varname}
+@r{[}@var{\varname\}@r{]}
+@end macro
+@defmac AM_PATH_GPGME (@ovar{minimum-version}, @ovar{action-if-found}, @ovar{action-if-not-found})
+Check whether @acronym{GPGME} (at least version @var{minimum-version},
+if given) exists on the host system.  If it is found, execute
+@var{action-if-found}, otherwise do @var{action-if-not-found}, if
+given.
+
+Additionally, the function defines @code{GPGME_CFLAGS} to the flags
+needed for compilation of the program to find the @file{gpgme.h}
+header file, and @code{GPGME_LIBS} to the linker flags needed to link
+the program to the @acronym{GPGME} library.
+@end defmac
+
+You can use the defined Autoconf variables like this in your
+@file{Makefile.am}:
+
+@example
+AM_CPPFLAGS = $(GPGME_CFLAGS)
+LDADD = $(GPGME_LIBS)
