# @BLURB: A common, simple eclass for Python packages.
|
| 12 |
# @DESCRIPTION:
|
| 13 |
# A common eclass providing helper functions to build and install
|
| 14 |
# packages supporting being installed for multiple Python
|
| 15 |
# implementations.
|
| 16 |
#
|
| 17 |
# This eclass sets correct IUSE and REQUIRED_USE. It exports PYTHON_DEPS
|
| 18 |
# and PYTHON_USEDEP so you can create correct dependencies for your
|
| 19 |
# package easily. It also provides methods to easily run a command for
|
| 20 |
# each enabled Python implementation and duplicate the sources for them.
|
| 21 |
#
|
| 22 |
# Please note that python-r1 will always inherit python-utils-r1 as
|
| 23 |
# well. Thus, all the functions defined there can be used
|
| 24 |
# in the packages using python-r1, and there is no need ever to inherit
|
| 25 |
# both.
|
| 26 |
#
|
| 27 |
# For more information, please see the python-r1 Developer's Guide:
|
| 28 |
# http://www.gentoo.org/proj/en/Python/python-r1/dev-guide.xml

# depend on another Python package being built for the same Python
|
| 118 |
