[-- Attachment #1.1: Type: Text/Plain, Size: 903 bytes --]

Members of Gentoo Python Project have agreed to deprecate the following functions
in EAPI <=2:
  - python_version()
  - python_mod_exists()
  - python_tkinter_exists()
  - distutils_python_version()
  - distutils_python_tkinter()

These functions are already banned in EAPI >=3.

1. In this week, these functions will start printing deprecation warnings in older EAPIs.
2. On 2010-07-01, these functions will start calling die().
   (If any ebuilds in gentoo-x86 still call any of these functions on 2010-07-01,
    then addition of calls to die() will be delayed.)
3. On 2011-01-01, these functions will be removed.

I will also send the announcement to gentoo-dev-announce mailing list to ensure
that developers not subscribed to gentoo-dev mailing list will notice the deprecation.
The attached patch shows text of deprecation warnings.
