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`.
