Generate an AWS CDK Typescript docset for Dash or Zeal, based on the published docs on docs.aws.amazon.com

This code depends on Python 3, plus a number of libraries. You can install Python with asdf by running asdf install, or you can manage that by other means.

1. Install a compatible version of Python:

   $ asdf install

2. Install packages:

   pip install -r requirements.txt

3. Run ./gen_docset.sh

This step uses wget --recursive to find and download all the docs from docs.aws.amazon.com. It may take a while.

There are a few things going on here:

• Removing unwanted tags from the HTML (for example, we don't need <script> tags or unsightly headers in Dash)
• Building up an index of all the programming constructs for Dash to search through (as per the instructions here)
• Structuring it all as a .docset folder, ready for Dash to import
