+Deprecation Warning
+-------------------
+**tl;dr**  
+This project is no longer maintained.  It does not support Webpack 5.  
+
+**A bit more detail**  
+Any look at the [project activity](https://github.com/numical/script-ext-html-webpack-plugin/pulse) will show that I have not been able to maintain this project adequately.  
+The advent of version 5 of Webpack requires another bout of refactoring that I simply have no time for.  
+Consequently v2.15.0 will be the last version of this plugin.
+My thanks to all users, and especially to all contributors, of this plugin over the years.  
+My apologies to all those whose webpack 5 migration has been made more complicated by this decision.
+
+**But I still want to use the plugin...**  
+Feel free!  
+My last update works with versions of v4.44.2 of webpack and v4.5.0 of html-webpack-plugin.  
+Forkers feel free!  That's what the licence is for.  
+In fact, if you fork with an intention to support on-going development, let me know!
+I'll happily link to your repository here and offer some tips (main one: ditch backward compatibility - it's a pain).  
+I will formally archive this repository at the end of the 2020.
