+## Special rules for generating sources. Include this file when there
+## are multiple targets ('gen_sources') being created using a single
+## command. In this case, parallel build protection is required, and
+## is provided by this file using a reasonably generic ruleset. For
+## more info, see:
+##
+## http://sources.redhat.com/automake/automake.html#Multiple-Outputs
+##
+## If a single source is being created, then normal rules can be used;
+## using this parallel protection will not hurt, but it also won't help.
+##
+## Define the variable 'par_gen_command' to be the command that
+## creates the sources 'gen_sources' from the dependency files
+## 'gen_sources_deps'.
+##
+
+## These STAMPS will be removed upon "make clean", but are otherwise
+## not used.
