+# @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.
