+"""SWIG Static Binding Copier
+
+This script copies over the Python bindings generated by SWIG from the build
+directory to the source directory. Before using the script, make sure you have
+LLDB_USE_STATIC_BINDINGS set to OFF by looking at CMakeCache.txt in the LLDB
+build directory.
+
+The scripts knows the location of the static bindings in the source directory
+based on its own location. The build directory must be specified as a position
+argument.
+
+$ copy-static-bindings.py <path to LLDB build directory>
+
+Run this script whenever you're changing any of the .i interface files in the
+bindings directory.
