+#	$ cd /some/where/temporary
+#	$ git clone https://github.com/laurikari/tre.git
+#	$ sh /usr/src/external/bsd/tre/tre2netbsd tre `pwd`
+#	$ cd src/external/bsd/tre/dist
+#	$ cvs import src/external/bsd/tre/dist LAURIKARI tre-yyyymmdd
+#	>>> if any conflicts, merge, fix and commit them.
+#	>>> check out src/external/bsd/tre/dist.
+#	$ cd checked-out-directory
+#	>>> next step requires autoconf, automake, gettext, and libtool.
+#	$ utils/autogen.sh
+#	$ ./configure --prefix=/usr --without-alloca
+#	>>> merge newly generated files:
+#	>>> 	config.h	 into /usr/src/external/bsd/tre/include
+#	>>> 	lib/tre-config.h into /usr/src/external/bsd/tre/include
+#	>>> 	tre.pc		 into /usr/src/external/bsd/tre/lib
