title: How to commit many numbered old versions of a file
body: <p>I'm looking for an elegant way to populate Mercurial with different versions of the same program, from 50 old versions that have numbered filenames:
  prog1.py, prog2.py ... prog50.py
  For each version I'd like to retain the dates and original filename, perhaps in the change comment.</p>
  
  <p>I'm new to Mercurial and have searched without finding an answer.</p>
