+# Note [slotting support]
+# -----------------------
+# Gentoo's layout for binutils files is non-standard as Gentoo
+# supports slotted installation for binutils. Many tools
+# still expect binutils to reside in known locations.
+# binutils-config package restores symlinks into known locations,
+# like:
+#    /usr/bin/${CTARGET}-<tool>
+#    /usr/bin/${CHOST}/${CTARGET}/lib/ldscrips
+#    /usr/include/
+#
+# Note [tooldir hack for ldscripts]
+# ---------------------------------
+# Build system does not allow ./configure to tweak every location
+# we need for slotting binutils hence all the shuffling in
+# src_install(). This note is about SCRIPTDIR define handling.
+#
+# SCRIPTDIR defines 'ldscripts/' directory location. SCRIPTDIR value
+# is set at build-time in ld/Makefile.am as: 'scriptdir = $(tooldir)/lib'
+# and hardcoded as -DSCRIPTDIR='"$(scriptdir)"' at compile time.
+# Thus we can't just move files around after compilation finished.
+#
+# Our goal is the following:
+# - at build-time set scriptdir to point to symlinked location:
+#   ${TOOLPATH}: /usr/${CHOST} (or /usr/${CHOST}/${CTARGET} for cross-case)
+# - at install-time set scriptdir to point to slotted location:
+#   ${LIBPATH}: /usr/$(get_libdir)/binutils/${CTARGET}/${PV}
