# @BLURB: Provides common ebuild phases for oasis-based packages.
# @DESCRIPTION:
# Provides common ebuild phases for oasis-based packages.
# Most of these packages will just have to inherit the eclass, set their
# dependencies and the DOCS variable for base.eclass to install it and be done.
#
# It inherits multilib, findlib, eutils and base eclasses.
# Ebuilds using oasis.eclass must be EAPI>=3.
# @ECLASS-VARIABLE: OASIS_BUILD_DOCS
# @DESCRIPTION:
# Will make oasis_src_compile build the documentation if this variable is
# defined and the doc useflag is enabled.
# The eclass takes care of setting doc in IUSE but the ebuild should take care
# of the extra dependencies it may need.
# Set before inheriting the eclass.
# @ECLASS-VARIABLE: OASIS_BUILD_TESTS
# @DESCRIPTION:
# Will make oasis_src_configure enable building the tests if the test useflag is
# enabled. oasis_src_test will then run them.
# Note that you sometimes need to enable this for src_test to be useful,
# sometimes not. It has to be enabled on a per-case basis.
# The eclass takes care of setting test in IUSE but the ebuild should take care
# of the extra dependencies it may need.
# Set before inheriting the eclass.
# @ECLASS-VARIABLE: OASIS_NO_DEBUG
# @DESCRIPTION:
# Disable debug useflag usage. Old oasis versions did not support it so we allow
# disabling it in those cases.
# The eclass takes care of setting debug in IUSE.
# Set before inheriting the eclass.
# @ECLASS-VARIABLE: OASIS_DOC_DIR
# @DESCRIPTION:
# Specify where to install documentation. Default is for ocamldoc HTML.
# Change it before inherit if this is not what you want.
# EPREFIX is automatically prepended.
