title: Best way to let users know that your Github fork is no longer maintained (ie. it's been merged)?
body: <p>Three months ago I forked a github repository for a rubygem and added some features.  A fair number of people configured their Rails app to load that gem from my github repository.  Yesterday the author merged my work and released a new gem.</p>
  
  <p>I would like to notify people who are continuing to pull from my github repo that they should switch back to the main gem.</p>
  
  <p>I tried adding a 'post_install_message' to my version of the gemspec, but bundler apparently won't use that for gems loaded from paths or github.</p>
  
  <p>I could modify the code to print a warning to the log file, but that feels messy.</p>
  
  <p>I could just update the README, but that assumes people would actually read it on github.com.</p>
  
  <p>Wondering if there is a good/standard/preferred method for this sort of thing?</p>
  
  <p>EDIT:  Well, this bugged me enough I submitted a pull request to add this functionality to bundler for gems included via :git or :path.  We'll see what happens :)</p>
  
  <p>UPDATE: Yay! <a href="https://github.com/bundler/bundler/commit/f876162b3d067ba5a3522b60e75cf13a19124f9c" rel="nofollow">https://github.com/bundler/bundler/commit/f876162b3d067ba5a3522b60e75cf13a19124f9c</a></p>
