technical

• the generator scripts uses node.js and its package manager npm. code is written in coffeescript, which is javascript just with reduced syntax
• how to recreate the csv files
  • initialise the development environment once with "npm install" to install dependencies, which creates a node_modules directory in the current directory
  • see files under exe/, they are shell scripts and can be executed with ./exe/filename and contain configuration options
  • for other tools see "coffee js/filename"
• how to recreate kanji-viewer
  • requires the kanji directory from kanjivg to have been downloaded and saved under data/kanjivg
  • create data files with "./exe/update-viewer-data"
  • execute "./exe/update-viewer"
  • the result file is build from html/viewer-template.html
• good to know regarding unicode: multiple kanji components/radicals and kanji that look exactly the same exist at separate codepoints. see wikipedia: kangxi radical unicode
