// Usage: node parse.js
//
// Script that creates index.html out of web/template.html and README.md.
//
// It is written in JS because this code used to be executed on the client side.
// To install the Node.js and npm run:
// $ sudo apt install nodejs npm # On macOS use `brew install ...` instead.
//
// To install dependencies globally, run:
// $ npm install -g jsdom jquery showdown highlightjs@9.12.0
//
// If running on macOS and modules can't be found after installation add:
// export NODE_PATH=/usr/local/lib/node_modules
// to the ~/.bash_profile or ~/.bashrc file and run '$ bash'.
//
// To avoid problems with permissions and path variables, install modules
// into project's directory using:
// $ npm install jsdom jquery showdown highlightjs@9.12.0
//
// It is also advisable to add a Bash script into .git/hooks directory, that will
// run this script before every commit. It should be named 'pre-commit' and it
// should contain the following line: `./parse.js`.
