+# @SUPPORTED_EAPIS: 8

+# @BLURB: Provide LLVM_SLOT to build against slotted LLVM
+# @DESCRIPTION:
+# An eclass to reliably depend on a set of LLVM-related packages

+# 1. Set LLVM_COMPAT to the list of supported LLVM slots.
+# 2. Use llvm_gen_dep and/or LLVM_USEDEP to add appropriate

+# 3. Use llvm-r1_pkg_setup, get_llvm_prefix or LLVM_SLOT.
+#
+# The eclass sets IUSE and REQUIRED_USE. The flag corresponding
+# to the newest supported stable LLVM slot is enabled by default.
+#
+# Example:
+# @CODE
+# LLVM_COMPAT=( {16..18} )
+#
+# inherit llvm-r1
+#
+# DEPEND="
+# dev-libs/libfoo[${LLVM_USEDEP}]

+# @SUPPORTED_EAPIS: 8
+# @PROVIDES: llvm-utils
+# @BLURB: Provide LLVM_SLOT to build against slotted LLVM
+# @DESCRIPTION:
+# An eclass to reliably depend on a set of LLVM-related packages
+# in a matching slot. To use the eclass:
+#
+# 1. Set LLVM_COMPAT to the list of supported LLVM slots.
+# 2. Use llvm_gen_dep and/or LLVM_USEDEP to add appropriate
+# dependencies.
+# 3. Use llvm-r1_pkg_setup, get_llvm_prefix or LLVM_SLOT.
+#
+# The eclass sets IUSE and REQUIRED_USE. The flag corresponding
+# to the newest supported stable LLVM slot (or the newest testing,
+# if no stable slots are supported) is enabled by default.
+#
+# Example:
+# @CODE
+# LLVM_COMPAT=( {16..18} )
+#
+# inherit llvm-r1
+#
+# DEPEND="
+# dev-libs/libfoo[${LLVM_USEDEP}]
+# $(llvm_gen_dep '
+# sys-devel/clang:${LLVM_SLOT}
+# sys-devel/llvm:${LLVM_SLOT}

Changed in v3: added LLVM_OPTIONAL to avoid unconditionally setting
REQUIRED_USE when the ebuild doesn't require LLVM unconditionally.
It also controls pkg_setup export.
