+# @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.
