+GDB and Valgrind Usage
+~~~~~~~~~~~~~~~~~~~~~~
+
+When using GDB or valgrind on pacman, you will want to run it on the actual
+binary rather than the shell script wrapper produced by libtool. The actual
+binary lives at `src/pacman/.libs/lt-pacman`, and will exist after running
+`./src/pacman/pacman` at least once.
+
+For example, to run valgrind:
+
+    ./src/pacman/pacman
+    valgrind --leak-check=full -- src/pacman/.libs/lt-pacman -Syu
