+# This script is meant to run from src directory in the same fashion than
+# subsurface/scripts/build.sh

+# Flags:	-t (--tag) A git valid tag, commit, etc in subsurface tree
+#		-j (--jobs) Desired build parallelism, integer.
+#		-b (--build) Cmake build type, valid values Debug or Release
+# Examples:
+#     $	./subsurface/scripts/build-smtk2ssrf.sh
+#	No flags, will build a Release version, with -j4 parallelism in the
+#	last set git tree position. This should be the usual use form.
+#     $	./subsurface/scripts/build-smtk2ssrf.sh -j 2 -t v4.6.5 -b Debug

+#	exists) with -j2 parallelism.
