# @BLURB: A common, simple eclass for Python packages.
|
|
|
|
# @DESCRIPTION:
|
|
|
|
# A common eclass providing helper functions to build and install
|
|
|
|
# packages supporting being installed for multiple Python
|
|
|
|
# implementations.
|
|
|
|
#
|
|
|
|
# This eclass sets correct IUSE and REQUIRED_USE. It exports PYTHON_DEPS
|
|
|
|
# and PYTHON_USEDEP so you can create correct dependencies for your
|
|
|
|
# package easily. It also provides methods to easily run a command for
|
|
|
|
# each enabled Python implementation and duplicate the sources for them.
|
|
|
|
#
|
|
|
|
# Please note that this eclass is mostly intended to be extended
|
|
|
|
# on-request. If you find something you used in other eclasses missing,
|
|
|
|
# please don't hack it around and request an enhancement instead.

# an absolute system path (it must start with a slash, and ${D} will be
|
|
|
|
# prepended to it) or relative to the implementation's site-packages directory
|

|
|
# (then it must start with a non-slash character).
|
|
|
|
#
|
|
|
|
# When unset, the modules will be installed in the site-packages root.
|
|
|
|
#
|
|
|
|
# Can be set indirectly through the python_moduleinto() function.

|
|

|
# Alternatively, you can set the variable directly.
