+# I got tired of the turnaround time when debugging my code, and I don't want
+# to make a full build system or frankly even maintain a ./build.sh script for
+# each project. I'm well on the road to re-inventing another build system, but
+# if we can make python a simple ./<my code>.py, why can't we do the same for
+# C and C++?
+#
+# See hello-world.cpp for the source code. Install this guy wherever your bins
+# are stored, try it, weep, then rejoice that you have one less buffer open.
