+Updating Duktape
+================
+
+1.  Fetch the [latest release](http://duktape.org/download.html) archive.
+
+2.  Extract it somewhere.
+
+3.  That extracts to a `duktape-[VERSION]` directory.
+
+4.  We need to tell duktape about our `duk_custom.h` header:
+
+    1.  Change into the `duktape-[VERSION]` directory.
+
+    2.  Run the following command:
+
+            python2 tools/configure.py \
+              --output-directory /tmp/output \
+              --source-directory src-input \
+              --config-metadata config \
+              --fixup-line '#include "duk_custom.h"'
+
+    3.  This generates a suitable set of duktape
+        sources in `/tmp/output`
+
+5.  Replace the `duktape.c`, `duktape.h` and
+    `duk_config.h` files in the netsurf source
+    tree (in `content/handlers/javascript/duktape`)
+    with those generated in `/tmp/output`.
