+## Entry rule for running SWIG
+
+uhd_swig.h uhd_swig.py uhd_swig.cc: uhd_swig.i
+## This rule will get called only when MAKE decides that one of the
+## targets needs to be created or re-created, because:
+##
+## * The .i file is newer than any or all of the generated files;
+##
+## * Any or all of the .cc, .h, or .py files does not exist and is
+## needed (in the case this file is not needed, the rule for it is
+## ignored); or
+##
+## * Some SWIG-based dependecy of the .cc file isn't met and hence the
+## .cc file needs be be regenerated. Explanation: Because MAKE
+## knows how to handle dependencies for .cc files (regardless of
+## their name or extension), then the .cc file is used as a target
+## instead of the .i file -- but with the dependencies of the .i
+## file. It is this last reason why the line:
+##
+## if test -f $@; then :; else
+##
+## cannot be used in this case: If a .i file dependecy is not met,
+## then the .cc file needs to be rebuilt. But if the stamp is newer
+## than the .cc file, and the .cc file exists, then in the original
+## version (with the 'test' above) the internal MAKE call will not
+## be issued and hence the .cc file will not be rebuilt.
+##
+## Once execution gets to here, it should always proceed no matter the
+## state of a stamp (as discussed in link above). The
+## $(DEPDIR)/uhd_swig-generate stuff is used to allow for parallel
+## builds to "do the right thing". The stamp has no relationship with
+## either the target files or dependency file; it is used solely for
+## the protection of multiple builds during a given call to MAKE.
+##
+## Catch signals SIGHUP (1), SIGINT (2), SIGPIPE (13), and SIGTERM
+## (15). At a caught signal, the quoted command will be issued before
+## exiting. In this case, remove any stamp, whether temporary of not.
+## The trap is valid until the process exits; the process includes all
+## commands appended via "\"s.
+##
+ trap 'rm -rf $(DEPDIR)/uhd_swig-generate-*' 1 2 13 15; \
+##
+## Create a temporary directory, which acts as a lock. The first
+## process to create the directory will succeed and issue the MAKE
