# Updates/generates the table of contents in markdown (wiki) files
# The first argument specifies the file(s) to process. If not given, all modified .md files in current folder are processed
# Keeps the files with Windows EOLs if run from MSYS (since markdown-toc changes EOL in some lines)
#
# Uses markdown-toc module inside Node.js - https://github.com/jonschlinkert/markdown-toc, assumes that the module is
# installed globally, which is done by
# npm install -g markdown-toc
# Installation of Node.js including npm is straightforward from https://nodejs.org/en/download/
#
# The TOC is added after the line <!-- toc --> or replaces the existing TOC between this line and <!-- tocstop -->
