+libc++ is the LLVM C++ standard library, targeting C++11.
+This SlackBuild will produce a version of libc++ that uses the
+libc++abi ABI interface.
+
+Note that the experimental library is NOT built by this script.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
