+
+A simple package that depends on OpenBLAS32_jll, and sets up the
+forwarding for LP64 BLAS symbols on 64-bit architectures using
+`libblastrampoline` that ships with Julia. On 32-bit architectures,
+this package does nothing.
+
+This package makes the following possible:
+1. JLLs of libraries need an LP64 BLAS can now link to libblastrampoline
+2. Users who want to use an LP64 BLAS will use libblastrampoline JLLs and include a dependency on OpenBLAS32.jl
+3. LP64 OpenBLAS will thus work out of the box as before
+4. However, since the underlying libraries are linked against libblastrampoline, users can also switch to different BLAS provider such as MKL or AppleAccelerate
