http://drupal.org/node/11517. I have done this using some command line magic:

find . -name README -exec cp '{}' '{}.txt' \; -exec cvs remove -f '{}' \; -exec cvs add '{}.txt' \;

I will update all occurences of 'README' to 'README.txt' in the conrtib CVS,
soon. I'll also rename LICENSE, CHANGELOG etc. files as soon as I get around
to it.

Updated to HEAD:
  - Updated to use the new menu system.
  - Removed instance of status().

- table(...) -> theme("table", ...")

- Bugfix: fixed the calls to menu().

- Bugfix: made the admin callback return its content.

- Feature module updates: added a MySQL scheme for the feature module,
  made it work with database prefixing, added support for the menu
  system changes.  Patch by Stefan.

- Updated to work with register_globals turned off.  Patch by Michael Frankowski.

- Updated to use the new menu system.

  'theme("function")' instead of '$theme->function()'.  Hopefully I didn't
  break anything.  If I did, let me know.

  The following modules need special attention (but should still work as is):

  1. The ldap_integration directory has its own user.module; I haven't updated
     the documentation bit that talks about themes.

  2. The hotlist module uses '$theme->hotlist_del_icon'.  Should be avoided
     and somehow wrapped in a (larger) call to theme().

  3. The image module has its own way of doing what 'theme()' does (or the
     former 'theme_invoke()').  Constructs like the one below (a) look wrong
     and (b) should be rewritten to properly use 'theme()'.  For example:

     $theme->box("foo", method_exists("bar") ? $theme->bar() : $bar);

     Search for "image_gallery_album", "image_gallery_home" and
     "image_thumb_browser".  I've already changed '$theme->box()' to
     'theme()'.

  4. The sidebar module uses '$theme->foreground' and '$theme->background'.
     Should be avoided and somehow wrapped in a (larger) call to theme().

  5. The org_informations module uses '$theme->separator()', which is new to
     me.

  6. The taxonomy_filter module uses '$theme->taxolist_filter_item()'.  It
     should use 'theme("taxolist_filter_item")' instead.  I haven't changed
     it because it would probably fail to resolve the default function if
     not overridden by a theme.

  7. The taxonomy_dhtml module's INSTALL file still talks about
     '$theme->image'.

  8. The xloadtree module's INSTALL file still talks about '$theme->image'.

  9. I haven't updated the style.module; too many $theme's, though I don't
     think it needs any updates.

  [I'll try to update the sandboxes later on.]
