Sun Feb 14 18:53:11 2010 UTC (4 years, 2 months ago) by arfrever
Branch: MAIN
Changes since 1.88: +11 -15 lines
Depend on >=app-admin/eselect-python-20091230, which allows to use --ABI option of `eselect python show`.
Set PYTHON_SCRIPT_NAME variable in wrapper scripts generated by python_generate_wrapper_scripts().
Simplify PYTHON() by using of --ABI option of `eselect python show`.
Fix checks for Jython and improve messages in python_mod_optimize().
